zlib

I decided I wanted to learn how to use compression in my programs, so I downloaded ZLib, and did all the stuff to makke it work with my compiler....

Ok, I got it working right, but I am not exactly sure how to use it...

I have this so far, which works fine, but I am not sure if it's the right way....

#include <iostream>
#include "zlib.h"
#include <conio.h>
using namespace std;
//int compress (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen); 
//int uncompress (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen); 

int main()
{
    unsigned char * d;
    const unsigned char  s[5] = "test";
    unsigned long ss = 5;
    unsigned long ds = 100;
    compress(d, &ds, s, ss);
    unsigned char * d2;
    unsigned long ss2 = 5;
    unsigned long ds2 = 100;
    uncompress(d2, &ds2, d, ds);
    cout << d2;

    getch();
    return 0;
}

that works fine... I get a nice "test" out on the screen.. but like I said, I don't know if that is right....



Thanks,
Dennis
