### DESCRIPTION

.Bf -symbolic These interfaces are obsoleted by **random**(3).

.Ef The ` rand` 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 ) .

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.
