rand
RAND(3) BSD Library Functions Manual RAND(3)NAME
rand, rand_r, srand, sranddev -- bad random number generator
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdlib.h>
int
rand(void);
int
rand_r(unsigned *seed);
void
srand(unsigned seed);
void
sranddev(void);
DESCRIPTION
These interfaces are obsoleted by arc4random(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 seed 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.
The sranddev() function initializes a seed, using the random(4) random number device which returns good random numbers. However, the rand()
function still remains unsuitable for cryptographic use.
The rand_r() function provides the same functionality as rand(). A pointer to the context value seed must be supplied by the caller.
SEE ALSO arc4random(3), random(3), random(4)STANDARDS
The rand() and srand() functions conform to ISO/IEC 9899:1990 (``ISO C90'').
The rand_r() function is as proposed in the POSIX.4a Draft #6 document.
