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 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).

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.
