rand_r(3)                                                         rand_r(3)

NAME
     randr - thread-safe pseudo-random number generator

SYNOPSIS
     #include <stdlib.h>

     int randr(unsigned int *seed);

DESCRIPTION
     The randr() function is the thread-safe version of rand().

     The randr() function computes a sequence of pseudo-random integers in
     the range 0 to RANDMAX. (The value of the RANDMAX macro will be at
     least 32767.)

     If randr() is called with the same initial value for the object
     pointed to by seed and that object is not modified between successive
     returns and calls to randr(), the same sequence shall be generated.

RETURN VALUE
     The randr() function returns a pseudo-random integer.

ERRORS
     No errors are defined.
