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).

SEE ALSO

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

NOTES

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

PORTABILITY

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