C++ (Cpp) key_checkch Examples

Example #1

File: KEY.C Project: NonCreature0714/descent2

// If not installed, uses BIOS and returns getch();
//	Else returns pending key (or waits for one if none waiting).
int key_getch()
{
	int dummy=0;
	
	if (!Installed)
		return getch();

	while (!key_checkch())
		dummy++;
	return key_inkey();
}

Example #2

File: key.c Project: paud/d2x-xl

int key_getch()
{
	int dummy=0;

	if (!bInstalled)
		return 0;
//		return getch();

	while (!key_checkch())
		dummy++;
	return KeyInKey();
}

Example #3

File: key.cpp Project: Admiral-MS/fs2open.github.com

// If not installed, uses BIOS and returns getch();
//	Else returns pending key (or waits for one if none waiting).
int key_getch()
{
	int dummy=0;
	int in;

	if ( !key_inited ) return 0;
	
	while (!key_checkch()){
		os_poll();

		dummy++;
	}
	in = key_inkey();

	return in;
}

Example #4

File: key.c Project: Ringdingcoder/d1x

int key_getch()
{
	int dummy=0;

	if (!Installed)
		return 0;
	//		return getch();

	while (!key_checkch()){
		dummy++;
