RAND(3C)RAND(3C)NAME
rand, srand - random number generator
SYNOPSIS
#include <stdlib.h>
void srand(int seed);
int rand(void);
DESCRIPTION
The newer random(3) should be used in new applications; rand remains
for compatibility.
Rand uses a multiplicative congruential random number generator with
period 2**32 to return successive pseudo-random numbers in the range
from 0 to (2**31)−1
The generator is reinitialized by calling srand with 1 as argument. It
can be set to a random starting point by calling srand with whatever
you like as argument.
RETURN VALUE
The srand function returns no value. The rand function computes a
sequence of psuedo-random integers.
