NAME

key_defined - obtain key code for an ncurses function key definition

SYNOPSIS

#include <curses.h>

int key_defined(const char * definition);

DESCRIPTION

The key_defined ncurses extension permits a curses application to determine the function key code, if any, to which the string definition is bound.

RETURN VALUE

key_defined returns the first key code to which definition is bound if any exists. If none does, it returns 0. If definition is a prefix of another bound definition, key_defined returns -1.

EXTENSIONS

key_defined is an ncurses extension.

PORTABILITY

Applications employing ncurses extensions should condition their use on the visibility of the NCURSES_VERSION preprocessor macro.
