NAME

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

SYNOPSIS

       #include <menu.h>

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

DESCRIPTION

       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 driver(3MENU).

       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

       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)).

PORTABILITY

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