srand() -- Random-Number Function (libc)

Seed random number generator
#include <stdlib.h>
void srand(seed) int seed;

srand()  uses seed  to  initialize the  sequence  of pseudo-random  numbers
returned  by   rand().  Different  values  of   seed  initialize  different
sequences.

srand()  cannot be  used  with any  of  the ``rand48''  functions.  For  an
overview of these functions, see the entry for srand48().
