Hi. I'm new to Perl XS. I have worked on perl for years.But i have only basic knowledge in C. I'm trying to create a C program say test.c and inside it I have a print array function which accepts an array and loops and print. I have created a corresponding test.xs file. and .pm file. I have made and installed it. When I try to use it it works for char array , but when I print an int array.. it doesn't. Please find the code below

#!/usr/bin/env perl

use ExtUtils::testlib;
use Data::Dumper;
use myClibs;

print "Compiling C program...\n";
print qx{compile.sh};

my $test = [ 1, 2, 3, 4, 5, 6, 9];

ArrayTest::print_array_char( "revendar" );
print "------------------------------------------------\n";
ArrayTest::print_array_char( @$test  );
print "------------------------------------------------\n";
ArrayTest::print_array_int( "revendar",8 );
print "------------------------------------------------\n";
ArrayTest::print_array_int( @$test ,8 );

C prog is functions.c

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


void print_array_char(char * array) {
        int l;
        int i;
        l=strlen(array);
        printf("Length of array is %d\n",l);

        for(i=0;i < l;i++) {
                printf("Element array[%d] = %c\n",i,array[i]);
        }
}

void print_array_int(const int array[], int l) {
        int i;
        for(i=0;i < l;i++) {
                printf("Element array[%d] = %d\n",i,array[i]);
        }
}

xs file is myClibs.xs

#include "EXTERN.h"
#include "perl.h"
#include "XSUB.h"

#include "ppport.h"

MODULE = myClibs                    PACKAGE = ArrayTest

PROTOTYPES: ENABLE

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

void
print_array_char(array)
        char  *  array

void
print_array_int(array,l)
        char *  array
        int     l

pm file is myClibs.pm

package myClibs;
our $VERSION = '0.01';
require XSLoader;
XSLoader::load('myClibs', $VERSION);
1;

My question is.. Can I not just write a complex C program and write a simple xs file containing the function/datatype names and compile it. Do I need to learn perlguts to achieve what I want. I'm trying to write a c program to replace a perl function which is slow and handles huge data. I am at the gates waiting for a solution/advice
