This function will remove from the console event queue, any key-up events
|
|
that are pending. under Win95 key-up events will incorrectly be translated
|
|
into real key presses by the OS ReadFile() API call, which scanf() uses.
|
|
The WinNT version of ReadFile() correctly ignores them, of course. The
|
|
problem can occur when getch() is called to get a key, then scanf() is
|
|
called to obtain more input from stdin. On Win95 the key-up event that is
|
|
still left in the event queue will cause ReadFile() to think that the same
|
|
key was pressed again. Although, good programming practice dictates that
|
|
one shouldn't use both getch() and scanf() near each other in the same
|
|
program, the following function could help alleviate this key-up problem.
|
|
cscanf() does NOT suffer from this problem since it gets its input via
|
|
getch() and not ReadFile(). __flush_win95_keyup_events() should be called
|
|
before scanf() is called. Keep in mind that you must allow sufficient time
|
|
for the user to release the key so that the key-up event is inserted
|
|
before flushing the key-up events. Otherwise, the key-up event will occur
|
|
after scanf() is blocked and waiting inside ReadFile().
|
|
|
|
__flush_win95_keyup_events() returns the number of key-up events that it
|
|
removed from the queue.
