erand48_r3
Generate uniformly distributed pseudo-random numbers reentrantly
Part of drand48_r(3).
Usage
All functions
shown
above:
Library
Standard C library (libc, -lc)
Overview
These functions are the reentrant analogs of the functions described in drand48(3). Instead of modifying the global random generator state, they use the supplied data buffer.
Before the first use, this struct must be initialized, for example, by filling it with zeros, or by calling one of the functions srand48_r(), seed48_r(), or lcong48_r().
Return value
The return value is 0.
