This is an extension to the curses library. It permits an
application to determine if a string is currently bound to any
keycode.
ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ
If the string is bound to a keycode, its value (greater than
zero) is returned. If no keycode is bound, zero is returned. If
the string conflicts with longer strings which are bound to keys,
-1 is returned.
ПЕРЕНОСИМОСТЬ
These routines are specific to ncurses. They were not supported
on Version 7, BSD or System V implementations. It is recommended
that any code depending on them be conditioned using
NCURSES_VERSION.
