 Q: Problem with using erand48.

I wish to generate several independent streams of pseudo-random numbers,
that is, the sequence  of  numbers in  each stream will not depend upon
how many times the routines have been called to generate  numbers  for  the  
other streams.

I am using erand48() for the above purpose, I have also declared an array
of unsigned short integers as mentioned in the man pages.

An example program is as follows:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

int i;
double random;
unsigned short x[3];

random = erand48(x);

random = erand48(x);


The output of the above program are negative numbers like -134219272.000000.

If anyone has any experience with erand48, any suggestion or help will
be appreciated. By the way, I am working on a Sun Sparc workstation(running openwin)
and am using gcc as my compiler.

Thanks again,
