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