.SH DESCRIPTION
These functions are the reentrant analogs of the functions described in
Instead of modifying the global random generator state, they use
the supplied data
.IR buffer .

Before the first use, this struct must be initialized, for example,
by filling it with zeros, or by calling one of the functions
.BR srand48_r (),
