The __ctype_tolower_loc()
function shall return a pointer into an array of
characters in the current locale that contains lower case equivalents for each
character in the current character set. The array shall contain a total of
384
characters, and can be indexed with any signed or unsigned char (i.e. with an
index value between -128 and
255). If the application is multithreaded, the
array shall be local to the current thread.
This interface is not in the source standard; it is only in the binary standard.
The __ctype_tolower_loc() function shall return a pointer to the array of characters to be used for the ctype() family of functions (see <ctype.h>).
