RAND(3) BSD Programmer's Manual RAND(3)NAME
rand, srand - bad random number generator
SYNOPSIS
#include <stdlib.h>
void
srand(unsigned seed);
int
rand(void);
DESCRIPTION
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 re-
peatable by calling srand() with the same seed value.
If no seed value is provided, the functions are automatically seeded with
a value of 1.
SEE ALSOrandom(3)STANDARDS
The rand() and srand() functions conform to ANSI C X3.159-1989 (``ANSI C
'').
