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
       ASCII 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 NULL on error.  The function set_menu_pattern may return
       the following error codes:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

       E_BAD_ARGUMENT
	    Routine detected an incorrect or out-of-range argument.

       E_NO_MATCH
	    Character failed to match.

SEE ALSO
       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.
