Pushes a character onto the input queue.
#include <curses.h>
int ungetch (int ch);
int unget_wch (const wchar_t wch);
The ungetch subroutine pushes the single-byte character ch onto the head of the input queue.
The unget_wch subroutine pushes the wide character wch onto the head of the input queue.
One character of push-back is guaranteed. The result of successive calls without an intervening call to the getch or get_wch subroutine are unspecified.
| ch | |
| wch |
To force the key KEY_ENTER back into the queue, use:
ungetch(KEY_ENTER);
This subroutine is part of Base Operation System (BOS) Runtime.
The getch or wgetch (getch, mvgetch, mvwgetch, or wgetch Subroutine) subroutine.
