menu_pattern (3X)                                                                            menu_pattern (3X)



NAME
       menu_pattern - get and set 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
       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
       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).
