RAND(3C)                 DOMAIN/IX SYS5                  RAND(3C)



NAME
     rand, srand - random number generator

USAGE
     srand(seed)
     int seed;

     rand()


DESCRIPTION
     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.

     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 any integer as an argument.

NOTES
     Drand48(3C) provides a much better, though more elaborate,
     random-number generator.
