RAND(3)			 BSD Library Functions Manual		       RAND(3)

NAME
     rand, srand, rand_r — bad random number generator

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <stdlib.h>

     void
     srand(unsigned int seed);

     int
     rand(void);

     int
     rand_r(unsigned int *seed);

DESCRIPTION
     These interfaces are obsoleted by random(3).

     The rand() function computes a sequence of pseudo-random integers in the
     range of 0 to RAND_MAX (as defined by the header file <stdlib.h>).

     The srand() function sets its argument as the seed for a new sequence of
     pseudo-random numbers to be returned by rand().  These sequences are
     repeatable by calling srand() with the same seed value.

     If no seed value is provided, the rand() function is automatically seeded
     with a value of 1.

     The rand_r() function is a reentrant interface to rand(); the seed has to
     be supplied and is maintained by the caller.

SEE ALSO
     random(3), rnd(4)

STANDARDS
     The rand() and srand() functions conform to ANSI X3.159-1989
     (“ANSI C89”).  The rand_r() function conforms to IEEE Std 1003.1c-1995
     (“POSIX.1”).
