RAND(3) 	       FreeBSD 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 seed);

     int
     rand(void);

     int
     rand_r(unsigned *ctx);

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 seed 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 functions are automatically seeded with
     a value of 1.

     rand_r() provides the same functionality as rand().  A pointer to the
     context value ctx must be supplied by the caller.

SEE ALSO
     random(3)

STANDARDS
     The rand() and srand() functions conform to ISO/IEC 9899:1990
     (``ISO C89'').

     The rand_r() function is as proposed in the POSIX.4a Draft #6 document.
