This is what I use.

----
#include <sgtty.h>
#include <stdio.h>

main()
{
struct sgttyb stty;
struct sgttyb ostty;
char c;

/* put the console in RAW mode */
ioctl(0, TIOCGETP,&stty);
ostty = stty;
stty.sg_flags |= RAW;
ioctl(0,TIOCSETP,&stty);

while(1) {
c = getchar(); /* read a character. Will get each character as they are typed */
/*  do something with the character */
}

/* return the console to its original state */
ioctl(0,TIOCSETP,&ostty);
}
