define_key - define a keycode
int define_key(const char *definition, int keycode);
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 inter-
pret them just as it would the predefined codes in the
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.
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
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 con-
ditioned using NCURSES_VERSION.
