rand srand sranddev rand_r - bad random number generator
function computes a sequence of pseudo-random integers in the range of 0 to RAND_MAX (as defined by the header file In stdlib.h ) .
function sets its argument Fa 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 Fa seed value is provided, the functions are automatically seeded with a value of 1.
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.
function provides the same functionality as rand (.);
A pointer to the context value Fa ctx must be supplied by the caller.
function is as proposed in the POSIX.4a Draft #6 document.
