drand48_r

Name

drand48_r -- reentrantly generate pseudorandom numbers in a uniform distribution

Synopsis

#include <stdlib.h>

int drand48_r(struct drand48_data * buffer, double * result);

Description

The interface drand48_r() shall function in the same way as the interface drand48(), except that drand48_r() shall use the data in buffer instead of the global random number generator state.

Before it is used, buffer must be initialized, for example, by calling lcong48_r(), seed48_r(), or srand48_r(), or by filling it with zeroes.
