    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.
