.SH DESCRIPTION
|
|
|
|
|
This is an extension to the curses library.
|
|
|
|
|
It permits an application to define keycodes with their corresponding control
|
|
|
|
|
strings, so that the ncurses library will interpret them just as it would
|
|
|
|
|
the predefined codes in the terminfo database.
|
|
|
|
|
.PP
|
|
|
|
|
If the given string is null, any existing definition for the keycode is
|
|
|
|
|
removed.
|
|
|
|
|
Similarly, if the given keycode is negative or zero, any existing string
|
|
|
|
|
for the given definition is removed.
|
|
|
|
|
.SH RETURN VALUE
|
2014-02-28 19:18:07 +00:00
|
|
|
The keycode must be greater than zero, and the string non-null,
|
|
|
|
|
otherwise ERR is returned.
|
|
|
|
|
ERR may also be returned if there is insufficient memory to allocate the
|
|
|
|
|
data to store the definition.
|
|
|
|
|
If no error is detected, OK 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.
