Thread: Implenting Function Keys

hmmm, thats something like what i would want, but i thought there was a simpler way in getting to implement them, like from a library, but thanks for all the help and new tips i learnt..

You can simplify that, but you still need a bunch of defines.

Code:

#include <conio.h>

// Name some control-codes
#define KEY_BEL        7
#define KEY_BS         8
#define KEY_TAB        9
#define KEY_LF        10
#define KEY_CR        13
#define KEY_ESC       27
#define KEY_DEL      127

// If 0 proceeds extended code, add 256
#define KEY_F1        59 + 256
#define KEY_F2        60 + 256
#define KEY_F3        61 + 256
#define KEY_F4        62 + 256
#define KEY_F5        63 + 256
#define KEY_F6        64 + 256
#define KEY_F7        65 + 256
#define KEY_F8        66 + 256
#define KEY_F9        67 + 256
#define KEY_F10       68 + 256

// If 224 proceeds extended code, add 512
#define KEY_F11      133 + 512
#define KEY_F12      134 + 512
#define KEY_HOME      71 + 512
#define KEY_UP        72 + 512
#define KEY_PAGEUP    73 + 512
#define KEY_LEFT      75 + 512
#define KEY_RIGHT     77 + 512
#define KEY_END       79 + 512
#define KEY_DOWN      80 + 512
#define KEY_PAGEDOWN  81 + 512
#define KEY_INSERT    82 + 512
#define KEY_DELETE    83 + 512

int get_key() {
    int c = getch();
    switch (c) {
      case 0:   return getch() + 256;
      case 224: return getch() + 512;
    }
    return c;
}

int main() {
    int c;
    while ((c = get_key()) != KEY_ESC) {
        printf( "%d\n", c);
    }
}
