An implementation of this version of the specification may not claim to be an implementation of the Linux Standard Base unless it has successfully completed the compliance process as defined by the Free Standards Group. _________________________________________________________ Introduction The LSB defines a binary interface for application programs that are compiled and packaged for LSB-conforming implementations on many different hardware architectures. Since a binary specification shall include information specific to the computer processor architecture for which it is intended, it is not possible for a single document to specify the interface for all possible LSB-conforming implementations. Therefore, the LSB is a family of specifications, rather than a single one. This document should be used in conjunction with the documents it references. This document enumerates the system components it includes, but descriptions of those components may be included entirely or partly in this document, partly in other documents, or entirely in other reference documents. For example, the section that describes system service routines includes a list of the system routines supported in this interface, formal declarations of the data structures they use that are visible to applications, and a pointer to the underlying referenced specification for information about the syntax and semantics of each call. Only those routines not described in standards referenced by this document, or extensions to those standards, are described in the detail. Information referenced in this way is as much a part of this document as is the information explicitly included here. The specification carries a version number of either the form x.y or x.y.z. This version number carries the following meaning: * The first number (x) is the major version number. All versions with the same major version number should share binary compatibility. Any addition or deletion of a new library results in a new version number. Interfaces marked as deprecated may be removed from the specification at a major version change. * The second number (y) is the minor version number. Individual interfaces may be added if all certified implementations already had that (previously undocumented) interface. Interfaces may be marked as deprecated at a minor version change. Other minor changes may be permitted at the discretion of the LSB workgroup. * The third number (z), if present, is the editorial level. Only editorial changes should be included in such versions. I.

Documentation Conventions _________________________________________________________ Chapter 1. Scope 1.1. General The Linux Standard Base (LSB) defines a system interface for compiled applications and a minimal environment for support of installation scripts. Its purpose is to enable a uniform industry standard environment for high-volume applications conforming to the LSB. These specifications are composed of two basic parts: A common specification ("LSB-generic") describing those parts of the interface that remain constant across all implementations of the LSB, and an architecture-specific specification ("LSB-arch") describing the parts of the interface that vary by processor architecture. Together, the LSB-generic and the architecture-specific supplement for a single hardware architecture provide a complete interface specification for compiled application programs on systems that share a common hardware architecture. The LSB-generic document shall be used in conjunction with an architecture-specific supplement. Whenever a section of the LSB-generic specification shall be supplemented by architecture-specific information, the LSB-generic document includes a reference to the architecture supplement. Architecture supplements may also contain additional information that is not referenced in the LSB-generic document. The LSB contains both a set of Application Program Interfaces (APIs) and Application Binary Interfaces (ABIs). APIs may appear in the source code of portable applications, while the compiled binary of that application may use the larger set of ABIs. A conforming implementation shall provide all of the ABIs listed here. The compilation system may replace (e.g. by macro definition) certain APIs with calls to one or more of the underlying binary interfaces, and may insert calls to binary interfaces as needed. The LSB is primarily a binary interface definition. Not all of the source level APIs available to applications may be contained in this specification. _________________________________________________________ 1.2. Module Specific Scope This is the Itanium architecture specific Core module of the Linux Standards Base (LSB). This module supplements the generic LSB Core module with those interfaces that differ between architectures. Interfaces described in this module are mandatory except where explicitly listed otherwise. Core interfaces may be supplemented by other modules; all modules are built upon the core. _________________________________________________________ Chapter 2. Normative References The specifications listed below are referenced in whole or in part by the Linux Standard Base. In this specification, where only a particular section of one of these references is identified, then the normative reference is to that section alone, and the rest of the referenced document is informative.

Requirements 3.1. Relevant Libraries The libraries listed in Table 3-1 shall be available on IA64 Linux Standard Base systems, with the specified runtime names. These names override or supplement the names specified in the generic LSB specification. The specified program interpreter, referred to as proginterp in this table, shall be used to load the shared libraries specified by DT_NEEDED entries at run time. Table 3-1. Standard Library Names Library Runtime Name libm libm.so.6.1 libdl libdl.so.2 libcrypt libcrypt.so.1 libz libz.so.1 libncurses libncurses.so.5 libutil libutil.so.1 libc libc.so.6.1 libpthread libpthread.so.0 proginterp /lib/ld-lsb-ia64.so.2 libgcc_s libgcc_s.so.1 These libraries will be in an implementation-defined directory which the dynamic linker shall search by default. _________________________________________________________ 3.2. LSB Implementation Conformance A conforming implementation shall satisfy the following requirements: * The implementation shall implement fully the architecture described in the hardware manual for the target processor architecture. * The implementation shall be capable of executing compiled applications having the format and using the system interfaces described in this document. * The implementation shall provide libraries containing the interfaces specified by this document, and shall provide a dynamic linking mechanism that allows these interfaces to be attached to applications at runtime. All the interfaces shall behave as specified in this document. * The map of virtual memory provided by the implementation shall conform to the requirements of this document. * The implementation's low-level behavior with respect to function call linkage, system traps, signals, and other such activities shall conform to the formats described in this document. * The implementation shall provide all of the mandatory interfaces in their entirety. * The implementation may provide one or more of the optional interfaces. Each optional interface that is provided shall be provided in its entirety. The product documentation shall state which optional interfaces are provided. * The implementation shall provide all files and utilities specified as part of this document in the format defined here and in other referenced documents. All commands and utilities shall behave as required by this document. The implementation shall also provide all mandatory components of an application's runtime environment that are included or referenced in this document. * The implementation, when provided with standard data formats and values at a named interface, shall provide the behavior defined for those values and data formats at that interface. However, a conforming implementation may consist of components which are separately packaged and/or sold. For example, a vendor of a conforming implementation might sell the hardware, operating system, and windowing system as separately packaged items. * The implementation may provide additional interfaces with different names. It may also provide additional behavior corresponding to data values outside the standard ranges, for standard named interfaces. _________________________________________________________ 3.3. LSB Application Conformance A conforming application shall satisfy the following requirements: * Its executable files are either shell scripts or object files in the format defined for the Object File Format system interface. * Its object files participate in dynamic linking as defined in the Program Loading and Linking System interface. * It employs only the instructions, traps, and other low-level facilities defined in the Low-Level System interface as being for use by applications. * If it requires any optional interface defined in this document in order to be installed or to execute successfully, the requirement for that optional interface is stated in the application's documentation. * It does not use any interface or data format that is not required to be provided by a conforming implementation, unless: + If such an interface or data format is supplied by another application through direct invocation of that application during execution, that application is in turn an LSB conforming application. + The use of that interface or data format, as well as its source, is identified in the documentation of the application. * It shall not use any values for a named interface that are reserved for vendor extensions. A strictly conforming application does not require or use any interface, facility, or implementation-defined extension that is not defined in this document in order to be installed or to execute successfully. _________________________________________________________ Chapter 4. Definitions For the purposes of this document, the following definitions, as specified in the ISO/IEC Directives, Part 2, 2001, 4th Edition, apply: can be able to; there is a possibility of; it is possible to cannot be unable to; there is no possibilty of; it is not possible to may is permitted; is allowed; is permissible need not it is not required that; no...is required shall is to; is required to; it is required that; has to; only...is permitted; it is necessary shall not is not allowed [permitted] [acceptable] [permissible]; is required to be not; is required that...be not; is not to be should it is recommended that; ought to should not it is not recommended that; ought not to _________________________________________________________ Chapter 5. Terminology For the purposes of this document, the following terms apply: archLSB The architectural part of the LSB Specification which describes the specific parts of the interface that are platform specific. The archLSB is complementary to the gLSB. Binary Standard The total set of interfaces that are available to be used in the compiled binary code of a conforming application. gLSB The common part of the LSB Specification that describes those parts of the interface that remain constant across all hardware implementations of the LSB. implementation-defined Describes a value or behavior that is not defined by this document but is selected by an implementor. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence of the value or behavior. An application that relies on such a value or behavior cannot be assured to be portable across conforming implementations. The implementor shall document such a value or behavior so that it can be used correctly by an application. Shell Script A file that is read by an interpreter (e.g., awk). The first line of the shell script includes a reference to its interpreter binary. Source Standard The set of interfaces that are available to be used in the source code of a conforming application. undefined Describes the nature of a value or behavior not defined by this document which results from use of an invalid program construct or invalid data input. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence or validity of the value or behavior. An application that relies on any particular value or behavior cannot be assured to be portable across conforming implementations. unspecified Describes the nature of a value or behavior not specified by this document which results from use of a valid program construct or valid data input. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence or validity of the value or behavior. An application that relies on any particular value or behavior cannot be assured to be portable across conforming implementations. Other terms and definitions used in this document shall have the same meaning as defined in Chapter 3 of the Base Definitions volume of ISO POSIX (2003). _________________________________________________________ Chapter 6. Documentation Conventions Throughout this document, the following typographic conventions are used: function() the name of a function command the name of a command or utility CONSTANT a constant value parameter a parameter variable a variable Throughout this specification, several tables of interfaces are presented. Each entry in these tables has the following format: name the name of the interface (symver) An optional symbol version identifier, if required. [refno] A reference number indexing the table of referenced specifications that follows this table. For example, forkpty(GLIBC_2.0) [1] refers to the interface named forkpty() with symbol version GLIBC_2.0 that is defined in the first of the listed references below the table.

Debug Information _________________________________________________________ Chapter 1. Machine Interface 1.1. Processor Architecture The Itanium(TM) Architecture is specified by the following documents * Itanium (TM) Architecture Software Developer's Manual Volume 1 * Itanium (TM) Architecture Software Developer's Manual Volume 2 * Itanium (TM) Architecture Software Developer's Manual Volume 3 * Itanium (TM) Architecture Software Developer's Manual Volume 4 * Itanium (TM) Software Conventions and Runtime Guide * Intel® Itanium (TM) Processor-specific Application Binary Interface Only the features of the Itanium(TM) processor instruction set may be assumed to be present. An application is responsible for determining if any additional instruction set features are available before using those additional features. If a feature is not present, then the application may not use it. Only instructions which do not require elevated privileges may be used. Applications may not make system calls directly. The interfaces in the C library must be used instead. There are some features of the Itanium(TM) processor architecture that need not be supported by a conforming implementation. These are described in this chapter. A conforming application shall not rely on these features. Applications conforming to this specification must provide feedback to the user if a feature that is required for correct execution of the application is not present. Applications conforming to this specification should attempt to execute in a diminished capacity if a required feature is not present. This specfication does not provide any performance guarantees of a conforming system. A system conforming to this specification may be implemented in either hardware or software. This specification describes only LP64 (i.e. 32-bit integers, 64-bit longs and pointers) based implementations. Implementations may also provide ILP32 (32-bit integers, longs, and pointers), but conforming applications shall not rely on support for ILP32. See section 1.2 of the Intel® Itanium (TM) Processor-specific Application Binary Interface for further information. _________________________________________________________ 1.2. Data Representation See Itanium (TM) Software Conventions and Runtime Guide Chapter 4. Within this specification, the term byte refers to an 8-bit object, the term halfword refers to a 16-bit object, the term word refers to a 32-bit object, the term doubleword refers to a 64-bit object, and the term quadword refers to a 128-bit object. Although the Itanium(TM) architecture also supports 120-bit addressable objects, this specification does not require LSB-conforming implementations to provide support for these objects. _________________________________________________________ 1.2.1. Byte Ordering LSB-conforming applications shall use little-endian byte ordering. LSB-conforming implementations may support big-endian applications. _________________________________________________________ 1.2.2. Fundamental Types Table 2-1 describes how fundemental C language data types shall be represented: Table 1-1. Scalar Types Type C sizeof Alignment (bytes) Notes Integral char 1 1 signed char unsigned char short 2 2 signed short unsigned short int 4 4 signed int unsigned int long 8 8 signed long unsigned long long long 8 8 See Note Below signed long long unsigned long long Pointer any-type * 8 8 any-type (*)() Floating-Point float 4 4 double 8 8 long double 16 16 Note: Support for the long long data type is dependent on support for ISO9899:1999 C language. This standard is not required for LSB-conformance, but this data type is important when developing applications for the Itanium(TM) architecture. The GNU Compiler Collection (gcc) includes support for long long of ISO9899:1999. A null pointer (for all types) shall have the value zero. _________________________________________________________ 1.2.3. Aggregates and Unions Aggregates (structures and arrays) and unions assume the alignment of their most strictly aligned component. The size of any object, including aggregates and unions, shall always be a multiple of the object's alignment. An array uses the same alignment as its elements. Structure and union objects may require padding to meet size and element constraints. The contents of such padding is undefined. * An entire structure or union object shall be aligned on the same boundary as its most strictly aligned member. * Each member shall be assigned to the lowest available offset with the appropriate alignment. This may require internal padding, depending on the previous member. * A structure's size shall be increased, if necessary, to make it a multiple of the alignment. This may require tail padding, depending on the last member. A conforming application shall not read padding. struct { char c; } Byte aligned, sizeof is 1 Offset Byte 0 0 c^0 Figure 1-1. Structure Smaller Than A Word struct { char c; char d; short s; int i; long l; } Doubleword Aligned, sizeof is 16 Offset Byte 3 Byte 2 Byte 1 Byte 0 0 s^2 d^1 c^0 4 i^0 8 l^0 12 Figure 1-2.

Internal and Tail Padding _________________________________________________________ 1.2.4. Bit Fields C struct and union definitions may have bit-fields, which define integral objects with a specified number of bits. Bit fields that are declared with neither signed nor unsigned specifier shall always be treated as unsigned. Bit fields obey the same size and alignment rules as other structure and union members, with the following additional properties: * Bit-fields are allocated from right to left (least to most significant). * A bit-field must entirely reside in a storage unit for its appropriate type. A bit field shall never cross its unit boundary. * Bit-fields may share a storage unit with other struct/union members, including members that are not bit fields. Such other struct/union members shall occupy different parts of the storage unit. * The type of unnamed bit-fields shall not affect the alignment of a structure or union, although individual bit-field member offsets shall obey the alignment constraints. Bit-field Type Width w Range signed char char unsigned char 1 to 8 -2^w-1 to 2^w-1-1 0 to 2^w-1 0 to 2^w-1 signed short short unsigned short 1 to 16 -2^w-1 to 2^w-1-1 0 to 2^w-1 0 to 2^w-1 signed int int unsigned int 1 to 32 -2^w-1 to 2^w-1-1 0 to 2^w-1 0 to 2^w-1 signed long long unsigned long 1 to 64 -2^w-1 to 2^w-1-1 0 to 2^w-1 0 to 2^w-1 Figure 1-4.

Special Registers Intel® Itanium (TM) Processor-specific Application Binary Interface, section 3.3.5, defines required register initializations for process startup. _________________________________________________________ 4.2. Process Stack (on entry) As defined in Intel® Itanium (TM) Processor-specific Application Binary Interface, section 3.3.5, the return pointer register (rp) shall contain a valid return address, such that if the application program returns from the main entry routine, the implementation shall cause the application to exit normally, using the returned value as the exit status. Further, the unwind information for this "bottom of stack" routine in the implementation shall provide a mechanism for recognizing the bottom of the stack during a stack unwind. _________________________________________________________ 4.3. Auxiliary Vector The auxiliary vector conveys information from the operating system to the application. Only the terminating null auxiliary vector entry is required, but if any other entries are present, they shall be interpreted as follows. This vector is an array of the following structures. typedef struct { long int a_type; /* Entry type */ union { long int a_val; /* Integer value */ void *a_ptr; /* Pointer value */ void (*a_fcn) (void); /* Function pointer value */ } a_un; } auxv_t; The application shall interpret the a_un value according to the a_type.

The link editor will perform a logical "or" of the extension bits of each object when creating an executable so that it creates only a single .IA_64.archext section in the executable. .IA_64.pltoff This section holds local function descriptor entries. .IA_64.unwind This section holds the unwind function table. The contents are described in the Intel (r) Itanium (tm) Processor Specific ABI. .IA_64.unwind_info This section holds stack unwind and and exception handling information. The exception handling information is programming language specific, and is unspecified. .plt This section holds the Procedure Linkage Table. .sbss This section holds uninitialized data that contribute to the program''s memory image. Data objects contained in this section are recommended to be eight bytes or less in size. The system initializes the data with zeroes when the program begins to run. The section occupies no file space, as indicated by the section type SHT_NOBITS. The .sbss section is placed so it may be accessed using short direct addressing (22 bit offset from gp). .sdata This section and the .sdata1 section hold initialized data that contribute to the program''s memory image. Data objects contained in this section are recommended to be eight bytes or less in size. The .sdata and .sdata1 sections are placed so they may be accessed using short direct addressing (22 bit offset from gp). .sdata1 See .sdata. _________________________________________________________ 9.2.

These definitions are intended to supplement those provided in the referenced underlying specifications. This specification uses ISO/IEC 9899 C Language as the reference programming language, and data definitions are specified in ISO C format. The C language is used here as a convenient notation.

Unless otherwise noted, these interfaces shall be included in the source standard. Other interfaces listed above for libgcc_s shall behave as described in the referenced base document. _Unwind_DeleteException Name _Unwind_DeleteException -- private C++ error handling method Synopsis void _Unwind_DeleteException((struct _Unwind_Exception *object)); Description _Unwind_DeleteException() deletes the given exception object. If a given runtime resumes normal execution after catching a foreign exception, it will not know how to delete that exception. Such an exception shall be deleted by calling _Unwind_DeleteException(). This is a convenience function that calls the function pointed to by the exception_cleanup field of the exception header. _Unwind_ForcedUnwind Name _Unwind_ForcedUnwind -- private C++ error handling method Synopsis _Unwind_Reason_Code _Unwind_ForcedUnwind((struct _Unwind_Exception *object), _Unwind_Stop_Fn stop, void *stop_parameter); Description _Unwind_ForcedUnwind() raises an exception for forced unwinding, passing along the given exception object, which should have its exception_class and exception_cleanup fields set. The exception object has been allocated by the language-specific runtime, and has a language-specific format, except that it shall contain an _Unwind_Exception struct. Forced unwinding is a single-phase process. stop and stop_parameter control the termination of the unwind process instead of the usual personality routine query. stop is called for each unwind frame, with the parameteres described for the usual personality routine below, plus an additional stop_parameter. Return Value When stop identifies the destination frame, it transfers control to the user code as appropriate without returning, normally after calling _Unwind_DeleteException(). If not, then it should return an _Unwind_Reason_Code value. If stop returns any reason code other than _URC_NO_REASON, then the stack state is indeterminate from the point of view of the caller of _Unwind_ForcedUnwind(). Rather than attempt to return, therefore, the unwind library should use the exception_cleanup entry in the exception, and then call abort(). _URC_NO_REASON This is not the destination from. The unwind runtime will call frame's personality routine with the _UA_FORCE_UNWIND and _UA_CLEANUP_PHASE flag set in actions, and then unwind to the next frame and call the stop() function again. _URC_END_OF_STACK In order to allow _Unwind_ForcedUnwind() to perform special processing when it reaches the end of the stack, the unwind runtime will call it after the last frame is rejected, with a NULL stack pointer in the context, and the stop() function shall catch this condition. It may return this code if it cannot handle end-of-stack. _URC_FATAL_PHASE2_ERROR The stop() function may return this code for other fatal conditions like stack corruption. _Unwind_GetGR Name _Unwind_GetGR -- private C++ error handling method Synopsis _Unwind_Word _Unwind_GetGR((struct _Unwind_Context *context), int index); Description _Unwind_GetGR() returns data at index found in context. The register is identified by its index: 0 to 31 are for the fixed registers, and 32 to 127 are for the stacked registers. During the two phases of unwinding, only GR1 has a guaranteed value, which is the global pointer of the frame referenced by the unwind context. If the register has its NAT bit set, the behavior is unspecified. _Unwind_GetIP Name _Unwind_GetIP -- private C++ error handling method Synopsis _Unwind_Ptr _Unwind_GetIP((struct _Unwind_Context *context)); Description _Unwind_GetIP() returns the instruction pointer value for the routine identified by the unwind context. _Unwind_GetLanguageSpecificData Name _Unwind_GetLanguageSpecificData -- private C++ error handling method Synopsis _Unwind_Ptr _Unwind_GetLanguageSpecificData((struct _Unwind_Context *context), uint value); Description _Unwind_GetLanguageSpecificData() returns the address of the language specific data area for the current stack frame. _Unwind_GetRegionStart Name _Unwind_GetRegionStart -- private C++ error handling method Synopsis _Unwind_Ptr _Unwind_GetRegionStart((struct _Unwind_Context *context)); Description _Unwind_GetRegionStart() routine returns the address (i.e., 0) of the beginning of the procedure or code fragment described by the current unwind descriptor block. _Unwind_RaiseException Name _Unwind_RaiseException -- private C++ error handling method Synopsis _Unwind_Reason_Code _Unwind_RaiseException((struct _Unwind_Exception *object)); Description _Unwind_RaiseException() raises an exception, passing along the given exception object, which should have its exception_class and exception_cleanup fields set. The exception object has been allocated by the language-specific runtime, and has a language-specific format, exception that it shall contain an _Unwind_Exception. Return Value _Unwind_RaiseException() does not return unless an error condition is found. If an error condition occurs, an _Unwind_Reason_Code is returnd: _URC_END_OF_STACK The unwinder encountered the end of the stack during phase one without finding a handler. The unwind runtime will not have modified the stack. The C++ runtime will normally call uncaught_exception() in this case. _URC_FATAL_PHASE1_ERROR The unwinder encountered an unexpected error during phase one, because of something like stack corruption. The unwind runtime will not have modified the stack. The C++ runtime will normally call terminate() in this case. _URC_FATAL_PHASE2_ERROR The unwinder encountered an unexpected error during phase two. This is usually a throw, which will call terminate(). _Unwind_Resume Name _Unwind_Resume -- private C++ error handling method Synopsis void _Unwind_Resume((struct _Unwind_Exception *object)); Description _Unwind_Resume() resumes propagation of an existing exception object. A call to this routine is inserted as the end of a landing pad that performs cleanup, but does not resume normal execution. It causes unwinding to proceed further. _Unwind_SetGR Name _Unwind_SetGR -- private C++ error handling method Synopsis void _Unwind_SetGR((struct _Unwind_Context *context), int index, uint value); Description _Unwind_SetGR() sets the value of the register indexed for the routine identified by the unwind context. _Unwind_SetIP Name _Unwind_SetIP -- private C++ error handling method Synopsis void _Unwind_SetIP((struct _Unwind_Context *context), uint value); Description _Unwind_SetIP() sets the value of the instruction pointer for the routine identified by the unwind context _________________________________________________________ 1.9.

How to use this License for your documents _________________________________________________________ Appendix A. GNU Free Documentation License Version 1.1, March 2000 Copyright (C) 2000 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. _________________________________________________________ A.1. PREAMBLE The purpose of this License is to make a manual, textbook, or other written document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others. This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software. We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference. _________________________________________________________ A.2. APPLICABILITY AND DEFINITIONS This License applies to any manual or other work that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you". A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language. A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (For example, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them. The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, whose contents can be viewed and edited directly and straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup has been designed to thwart or discourage subsequent modification by readers is not Transparent. A copy that is not "Transparent" is called "Opaque". Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML designed for human modification. Opaque formats include PostScript, PDF, proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML produced by some word processors for output purposes only. The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text. _________________________________________________________ A.3. VERBATIM COPYING You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3. You may also lend copies, under the same conditions stated above, and you may publicly display copies. _________________________________________________________ A.4. COPYING IN QUANTITY If you publish printed copies of the Document numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects. If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages. If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a publicly-accessible computer-network location containing a complete Transparent copy of the Document, free of added material, which the general network-using public has access to download anonymously at no charge using public-standard network protocols. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public. It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document. _________________________________________________________ A.5. MODIFICATIONS You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version: A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has less than five). C. State on the Title page the name of the publisher of the Modified Version, as the publisher. D. Preserve all the copyright notices of the Document. E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below. G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice. H. Include an unaltered copy of this License. I. Preserve the section entitled "History", and its title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the "History" section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. K. In any section entitled "Acknowledgements" or "Dedications", preserve the section's title, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles. M. Delete any section entitled "Endorsements". Such a section may not be included in the Modified Version. N. Do not retitle any existing section as "Endorsements" or to conflict in title with any Invariant Section. If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles. You may add a section entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard. You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one. The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version. _________________________________________________________ A.6. COMBINING DOCUMENTS You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice. The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. In the combination, you must combine any sections entitled "History" in the various original documents, forming one section entitled "History"; likewise combine any sections entitled "Acknowledgements", and any sections entitled "Dedications". You must delete all sections entitled "Endorsements." _________________________________________________________ A.7. COLLECTIONS OF DOCUMENTS You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects. You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document. _________________________________________________________ A.8. AGGREGATION WITH INDEPENDENT WORKS A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, does not as a whole count as a Modified Version of the Document, provided no compilation copyright is claimed for the compilation. Such a compilation is called an "aggregate", and this License does not apply to the other self-contained works thus compiled with the Document, on account of their being thus compiled, if they are not themselves derivative works of the Document. If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one quarter of the entire aggregate, the Document's Cover Texts may be placed on covers that surround only the Document within the aggregate. Otherwise they must appear on covers around the whole aggregate. _________________________________________________________ A.9. TRANSLATION Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License provided that you also include the original English version of this License. In case of a disagreement between the translation and the original English version of this License, the original English version will prevail. _________________________________________________________ A.10. TERMINATION You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License. Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. _________________________________________________________ A.11. FUTURE REVISIONS OF THIS LICENSE The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/. Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. _________________________________________________________ A.12. How to use this License for your documents To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page: Copyright (c) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.1 or any later version published by the Free Software Foundation; with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. A copy of the license is included in the section entitled "GNU Free Documentation License". If you have no Invariant Sections, write "with no Invariant Sections" instead of saying which ones are invariant. If you have no Front-Cover Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being LIST"; likewise for Back-Cover Texts. If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
