Making proper wrappers.

Hope this isn't a stupid question, but Im trying to make a proper wrapper for printf.

I get the proper output doing the following:

Code:

---

text.hprintf("test\n");

---

The output is:

Code:

---

test

---

But I get a wierd output if I do:

Code:

---

text.hprintf("test\n%i", 123456789);

---

The output is:

Code:

---

test
1244892

---

Here's the small source.

main.cpp

Code:

---

//Alot of these includes are not used.
//Most will be used in the future.
#include <cstdlib>
#include <fstream>
#include <iostream>
#include <fstream>
#include <windows.h>
#include <cstring>
#include <time.h>
#include "output.h"

CTextOutput text;

int main(){
        char omfg;
        int i = 0;
        while(1){
                if(i==0)
                text.hprintf("test\n%i", 123456789);
                std::cin>>omfg;
                i=1;
                }
        return 0;
}

---

output.h

Code:

---

#ifndef OUTPUT_H
#define OUTPUT_H

class CTextOutput
        {

        private:
       
        public:

        int hprintf(const char* string, ...);
        int haprintf(const char* string, ...);

        };

#endif

---

output.cpp

Code:

---

#include <cstdlib>
#include <iostream>
#include <fstream>
#include <windows.h>
#include <string>
#include <cstring>
#include <time.h>
#include "output.h"

int CTextOutput::hprintf(const char* string, ...)
{
printf(string);
return 0;
}
int CTextOutput::haprintf(const char* string, ...)
{
printf("<<: ");
printf(string);
return 0;
}

---

This was my attempt at a custom wrapper. Any ideas?

1. my first question: why bother? use iostream class.

2. baring that, you need to use functions and macros in STDARG.H to access the optional parameters. See MSDN for example program.
