ungetch(3XCURSES)

NAME

ungetch, unget_wch - push character back onto the input queue

#include <curses.h> int ungetch(int ch);

int unget_wch(const wchar_t wch);

ch: Is the single byte character to be put back in the input queue for the next call to getch(3XCURSES).
wch: Is the wide character to be put back in the input queue for the next call to get_wch(3XCURSES).

The ungetch() function pushes ch back onto the input queue until the next call to getch().

The unget_wch() function is similar to ungetch() except that ch can be of type wchar_t.

On success, these functions return OK. Otherwise, they return ERR.

None.
