So, I have decided to experiment with _getch... Interestingly enough, I have found that there are different 'escape' values returned for different kinds of control keys...
-32 was returned for both the END and the Delete keys, and the following numbers represented their actual scan codes.
for F1 and F2, 0 was returned, and following, their scan codes.
This leads me to a particular question: Are these codes the same for every keyboard? I have doubts that they are...
I read up, and found a very nice post by duos. In his mini-article, he says that for control characters, 0 is returned to signify that a control character was pressed, and then the scan code is sent. Unfortunately, I saw nothing in there about there being different escape codes for different control keys. Furthermore, I find myself wondering if it could be OS-dependent...
Note: I did cast the codes as an integer (psudo code): char ch; cout<< int(ch);
so, to sum it up:
Are the escape/scan codes unique for each piece of hardware, or are they standardized?
The leading underscore on the name is the hint. It's platform/environment specific.
Scan codes are specific to a keyboard. Ad keyboard driver converts these to characters (in a character set).
Escape codes are standardised (see ANSI.sys). Scan codes are hardware specific, but there seems to be defacto standards, which would explain why you only need a keyboard driver for so special/unusual keyboard.
