RAND(3C) RAND(3C)
NAME
rand, srand - random number generator
SYNOPSIS
srand(seed)
int seed;
rand()
DESCRIPTION
The newer random(3) should be used in new applications; rand remains for compatibilty.
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 on the VAX, and (2**15)-1 on the PDP-11.
The generator is reinitialized by calling srand with 1 as argument. It can be set to a random starting point by calling srand with what-
ever you like as argument.
