C++ (Cpp) text_to_cursor Examples

Example #1

int

{
int pos;
int n;
    if (tw->quitnow)
	return ch;	/* don't write error message as we shut down */
    switch(ch) {

		if (tw->CursorFlag)

		break;
	case '\n':
		text_new_line(tw);
		break;
	case 7:
		MessageBeep(-1);
		if (tw->CursorFlag)
		    text_to_cursor(tw);
