The function returns the number of events waiting. This may be > 1
if the repeation of real keys pressed so far are > 1.
Keyboard: Returns 0 on NUMLOCK, CAPSLOCK, SCROLLLOCK.
Returns 0 on NUMLOCK, CAPSLOCK, SCROLLLOCK.
Returns 1 for SHIFT, ALT, CTRL only if no other key has been
pressed in between; these are returned on keyup in opposite
to normal keys. The overall flags for processing of SHIFT, ALT,
CTRL (SP->return_key_modifiers) must have been set.
Returns 1 for SHIFT, ALT, CTRL only if no other key has been pressed
in between, and SP->return_key_modifiers is set; these are returned
on keyup.
FGC: CHANGED BEHAVIOUR: In previous version SHIFT etc had a
chance to be returned on the first keydown, too. This was a
bug, because return_key_modifiers were 0.
Normal keys are returned on keydown only. The number of
repetitions are returned. Dead keys (diacritics) are
omitted. See below for a description.
The keypad entering of special keys is not supported. This
feature can be built in by replacing "#ifdef NUMPAD_CHARS"
with an intelligent code.
Mouse: MOUSE_MOVE without a pressed mouse key are ignored.
Normal keys are returned on keydown only. The number of repetitions
are returned. Dead keys (diacritics) are omitted. See below for a
description.
