keybound(3x)                     Library calls                    keybound(3x)

NAME

       keybound - get definition of a curses function key code

SYNOPSIS

       #include <curses.h>

       char * keybound(int key-code, int count);

DESCRIPTION

       The  keybound  ncurses extension permits a curses application to obtain
       the value of the  string  bound  to  the  function  key  key-code;  see
       wgetch(3x)  (wide-character API users: wget_wch(3x)).  By default, such
       bindings are string  capabilities  from  the  terminfo  database  entry
       corresponding   to   the  terminal  type.   The  application  can  non-
       destructively   and   repeatedly   override   such   definitions   with
       define_key(3x),  as  if  by  pushing new definitions onto a stack.  The
       count parameter accesses the  nth  most  recently  defined  binding;  0
       selects the binding that is used on input.

RETURN VALUE

       If key-code corresponds to a function key defined by the application or
       the terminal type in use, keybound allocates and returns a string  that
       must be freed by the application.  keybound returns NULL if key-code is
       not positive or if it does not correspond to a key code definition.

EXTENSIONS

       keybound is an ncurses extension.

PORTABILITY

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