menu_pattern(3X)                                        menu_pattern(3X)

NAME         top

       set_menu_pattern, menu_pattern - set and get a menu's pattern
       buffer

SYNOPSIS         top

       #include <menu.h>

       int set_menu_pattern(MENU *menu, const char *pattern);
       char *menu_pattern(const MENU *menu);

DESCRIPTION         top

       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.

RETURN VALUE         top

       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.

       E_BAD_ARGUMENT
            Routine detected an incorrect or out-of-range argument.

       E_BAD_STATE
            Routine was called from an initialization or termination
            function.

       E_NOT_CONNECTED
            No items are connected to menu.

       E_NO_MATCH
            Character failed to match.

       E_SYSTEM_ERROR
            System error occurred (see errno(3)).
