Ow yes that does look like an issue

Alright so here are my updates, I was also thinking that I need to change my command line ascii codes to actual integers like this.

Now I'm coming to think that this could perhaps lead to some memory issues, so I might also be obligated to throw in a *alloc.

Code:
int main( int argc, char** argv )
{
    int i = 3; // start with the 3rd value of argv
    int** crc_s; 
    
    // Some argument testing here

    while( argv[ i ] ) {
       crc_s[ i ] = malloc( sizeof(argv[i]) );
       if( crc_s[ i ] == NULL )
           exit( -1 );
       crc_s[ i ] = atoi( argv[ i ] ); // Perhaps this is a better way of doing it
    }

    crcSpoof( argv[1], argv[2], "fileOutTmp", NULL, NULL, crc_s );

Hopefully thats the proper way to allocate memory ( I have never really done much with allocating memory )

Digest::CRC(3)						User Contributed Perl Documentation					    Digest::CRC(3)

NAME

       Digest::CRC - Generic CRC functions

SYNOPSIS

	 # Functional style

	 use Digest::CRC qw(crc64 crc32 crc16 crcccitt crc crc8 crcopenpgparmor);
	 $crc = crc64("123456789");
	 $crc = crc32("123456789");
	 $crc = crc16("123456789");
	 $crc = crcccitt("123456789");
	 $crc = crc8("123456789");
	 $crc = crcopenpgparmor("123456789");

	 $crc = crc($input,$width,$init,$xorout,$refout,$poly,$refin,$cont);

	 # add data to existing

	 $crc = crc32("ABCD", $crc);

	 # OO style
	 use Digest::CRC;

	 $ctx = Digest::CRC->new(type=>"crc16");
	 $ctx = Digest::CRC->new(width=>16, init=>0x2345, xorout=>0x0000,
				 refout=>1, poly=>0x8005, refin=>1, cont=>1);

	 $ctx->add($data);
	 $ctx->addfile(*FILE);

	 $digest = $ctx->digest;
	 $digest = $ctx->hexdigest;
	 $digest = $ctx->b64digest;

DESCRIPTION

       The Digest::CRC module calculates CRC sums of all sorts.  It contains wrapper functions with the correct parameters for CRC-CCITT, CRC-16,
       CRC-32 and CRC-64, as well as the CRC used in OpenPGP's ASCII-armored checksum.
