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.
