NAME

6       set_menu_pattern, menu_pattern - set and get a menu's pattern buffer
7

SYNOPSIS

9       #include <menu.h>
10       int set_menu_pattern(MENU *menu, const char *pattern);
11       char *menu_pattern(const MENU *menu);
12

DESCRIPTION

14       Every  menu  has  an  associated pattern match buffer.  As input events
15       that are printable characters come in, they are appended to this  match
16       buffer and tested for a match, as described in menu_driver(3X).
17
18       The  function  set_menu_pattern  sets  the pattern buffer for the given
19       menu and tries to find the first matching item.  If it  succeeds,  that
20       item becomes current; if not, the current item does not change.
21
22       The function menu_pattern returns the pattern buffer of the given menu.
23

RETURN VALUE

25       The  function menu_pattern returns a pointer, which is NULL if the menu
26       parameter is NULL.  Otherwise, it is a pointer to  a  string  which  is
27       empty if no pattern has been set.  It does not set errno.
28
29       The function set_menu_pattern may return the following error codes:
30
31       E_OK The routine succeeded.
32
33       E_BAD_ARGUMENT
34            Routine detected an incorrect or out-of-range argument.
35
36       E_BAD_STATE
37            Routine was called from an initialization or termination function.
38
39       E_NOT_CONNECTED
40            No items are connected to menu.
41
42       E_NO_MATCH
43            Character failed to match.
44
45       E_SYSTEM_ERROR
46            System error occurred (see errno).
