- set and get a menu's pattern buffer
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 menu_driver
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
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:
The routine succeeded.
Routine detected an incorrect or out-of-range argument.
Routine was called from an initialization or termination function.
No items are connected to menu.
Character failed to match.
System error occurred (see errno).
The header file <menu.h>
automatically includes the header file
These routines emulate the System V menu library.
They were not supported on
Version 7 or BSD versions.
