Output to parallel port

I am trying to write a number to the parallel port data lines and when I use the following code, my program crashes.

#include <conio.h>
#define data 0x378

scanf("%i",&bits);
_outp(data,bits);

Any ideas?

Wow. You're lucky it compiles. You don't even have a main function... ;)

Quzah.

I do have a main function, I just didn't think that I needed to put that in aswel.

#include <conio.h>
#define data 0x378

int main(void)
{
scanf("%i",&bits);
_outp(data,bits);
}

Any ideas?

I have been looking into this one and have found out that because I am using Windows NT 4 I can not just use the windows drivers and must make my own with windows DDK.

Before I begin does anybody know of a way around this?
