.AT 3 rand, srand - bad random number generator

void
srand(seed)
unsigned int seed;

rand()

These interfaces are obsoleted by random(3).

The rand function computes a sequence of pseudo-random integers in the range of 0 to RAND_MAX (as defined by the header file <stdlib.h>).

The srand function sets its argument as the seed for a new sequence of pseudo-random numbers to be returned by rand . These sequences are repeatable by calling srand with the same seed value.

If no seed value is provided, the functions are automatically seeded with a value of 1.

Rand and srand conform to ANSI X3.159-1989 (``ANSI C''). random(3)
