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  argu-
            ment.

       E_BAD_STATE
            Routine was called from an initialization or termina-
            tion 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).

       were not supported on Version 7 or BSD versions.
