The rraanndd() function computes a sequence of pseudorandom integers in the
range of 0 to RAND_MAX (as defined by the header file <_s_t_d_l_i_b_._h>).
The ssrraanndd() function sets its argument as the seed for a new sequence of
pseudorandom numbers to be returned by rraanndd(). These sequences are re
peatable by calling ssrraanndd() with the same seed value.
If no seed value is provided, the functions are automatically seeded with
a value of 1.

The rraanndd() and ssrraanndd() functions conform to ANSI C3.1591989 (``ANSI
C'').
