XS Library - Embedding C code in Perl

ginttu has asked for the wisdom of the Perl Monks concerning the following question:

Hey! I am embedding some code written in C into Perl by the use of H2XS. I've been able to write little C programs like "Hello, World" and have the output come out of h2xs.

###############
# C code
# Hello, World
void 
print_hello (void)
{
   printf("Hello, World\n");
}
###############
# XS code
# Hello, World
#include "EXTERN.h"
#include "perl.h"
#include "XSUB.h"

MODULE = Hello         PACKAGE = Hello

void
print_hello()

Now the next C program I would like to use is very complex! Does anyone know how to pass parameters from my command line so I can use them with my *.xs code? Any help would be appreciated!! Also, does anyone have any examples using h2xs with C libraries?? Thanks, Jennifer
