RAND(3C) UNIX Programmer's Manual 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 gen- erator 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 cal- ling srand with whatever you like as argument.
