NAME

set_menu_pattern, menu_pattern - set and get 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*(3)).

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.
