trying to do something like the ts push to talk

Hey i'm trying to write a program that like teamspeak can catch keys even when they are not in focus.

I found a way to do it using things similar to a key logger.

I'm using this code


#include <iostream>
#include <sys/io.h>
#include <stdio.h>

using namespace std;

unsigned char c;
int i = 0;

int main( int argc, char *argv[] )
{
if(getuid() || getgid())
{
printf("Have to be root to perform a iopl()!\n");
exit(1);
}//perform root checks
if(iopl(3) == -1)
{
perror("iopl()");
printf("error!");
exit(1); //get required iopl level to access keyboard
}
do
{
c = NULL;
c = inb(0x60); //catch scan codes from keyboard
if (c != NULL)
cout << c << endl; //write scan code to screen
//fflush(0); //empty all??
}while (i == 0);
}

I'm not sure what fflush is meant to do here but im assuming its clearing all streams?

Anyways i ran this code and my computer threw a spazz. It started opening random things then it just stopped and nothing would respond so i held down the power button :S

I'm just trying to a program running in the background to receive the key signals (and still let the program in focus receive them as well).

What am I doing wrong???

My c is very rusty but would fflush (stdin) not accomplish this?

You should use:


fflush(stdout);

cause your want to print out to the standard output.

I'm more concerned about why my computer threw a spazz. Any idea's why this wouldnt print out the last key pressed scan code and instead makes my pc go crazy?
