keybound - return definition of keycode
char * keybound(int keycode, int count);
This is an extension to the curses library. It permits an application to
determine the string which is defined in the terminfo for specific keycodes.
The keycode parameter must be greater than zero, else NULL is returned.
If it does not correspond to a defined key, then NULL is returned. The
count parameter is used to allow the application to iterate through
multiple definitions, counting from zero. When successful, the function
returns a string which must be freed by the caller.
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.
