OpenDarwin 7.2.1 - man page for menu_pattern (opendarwin section 3x)

menu_pattern(3X)										     menu_pattern(3X)

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.
