   key_defined.3x    ( 3 )

проверьте, определен ли ключевой код (check if a keycode is defined)

Имя (Name)

key_defined - check if a keycode is defined

Синопсис (Synopsis)

#include <curses.h>


       int key_defined(const char *definition);

Описание (Description)

This is an extension to the curses library.  It permits an
       application to determine if a string is currently bound to any
       keycode.

Возвращаемое значение (Return value)

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.

Портативность (Portability)

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.
