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


   #include <menu.h>
   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 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.


   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).


   ncurses(3NCURSES), menu(3MENU).


   The  header  file  <menu.h>  automatically  includes  the  header  file


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