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).

       curses(3X), menu(3X).

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.
