normaly no, but ther is some way to change terminal behawiour... I didn't 
test it, but maybe it will work :

#include <stdio.h>
#include <termios.h>
#include <unistd.h>

int main ()
{
  struct termios przed, po;
  int c;
  tcgetattr (0, &przed); 
  po = przed;
  po.c_lflag &= ~(ICANON | ECHO); 
  tcsetattr (0,TCSANOW, &po);
  do {
    c = getchar();
    printf ("Key: %c\n", c);
  } while (c != 'q');
  tcsetattr (0, TCSANOW, &przed); 
  return 0;
}
