pattern (3menu)

#include <menu.h>

int set_menu_pattern(MENU *menu, const char *pattern);

char *menu_pattern(const MENU *menu);

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 driver(3MENU).

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.

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).

ncurses(3NCURSES), menu(3MENU).

The header file <menu.h> automatically includes the header file <curses.h>.

These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
