setstate() -- allows rapid switching between random number state arrays

SYNOPSIS

#include <stdlib.h>

char * setstate(char * arg_sate);

The setstate() function allows rapid switching between random number state arrays. The state arrays must be initialized by the initstate() function. The array defined by the arg_state parameter is used for further random-number generation until the initstate() function is called or the setstate() function is called again. The setstate() function returns a pointer to the previous state array.
