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 error codes:
E_OK The routine succeeded.
Routine detected an incorrect or out-of-range argument.
Routine was called from an initialization or termination function.
No items are connected to menu.
Character failed to match.
System error occurred (see errno).

These routines emulate the System V menu library. They were not sup‐
ported on Version 7 or BSD versions.
