menu_pattern - get and set a menu's pattern buffer
int set_menu_pattern(MENU *menu, const char *pattern);
char *menu_pattern(const MENU *menu);
Every menu has an associated pattern match buffer. As
input events that are printable characters come in, they
are appended to this match buffer and tested for a match,
as described in menu_driver(3x).
The function set_menu_pattern sets the pattern buffer for
the given menu and tries to find the first matching item.
If it succeeds, that item becomes current; if not, the
current item does not change.
The function menu_pattern returns the pattern buffer of
the given menu.
The function menu_pattern returns a pointer, which is NULL
if the menu parameter is NULL. Otherwise, it is a pointer
to a string which is empty if no pattern has been set. It
does not set errno.
The function set_menu_pattern may return the following
