SYNOPSIS

#include <stdlib.h>

void srand(unsigned int seed);

---

DESCRIPTION

The srand() function uses the argument seed as a seed for a new sequence of pseudo-random numbers to be returned by subsequent calls to rand(). Then, if srand() is called with the same seed value, the same sequence of pseudo-random numbers is repeated. If rand() is called before any calls to srand() have been made, the same sequence is generated as when srand() is first called with a seed value of 1.
