`long random(void)`

The random() function computes a sequence of pseudo-random integers
in the range of 0 to `RANDOM_MAX`

(as defined by the
header file <stdlib.h>).

The srandom() 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 srandom() with the same seed value.

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