menu_pattern (3) ( Linux man: Библиотечные вызовы )
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.
