menu_pattern - get and set a menu’s pattern buffer |
#include <menu.h> |
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. |
The function menu_pattern returns NULL on error. The function set_menu_pattern may return the following error codes: |
E_OK |
The routine succeeded. |
E_SYSTEM_ERROR |
System error occurred (see errno). |
E_BAD_ARGUMENT |
Routine detected an incorrect or out-of-range argument. |
E_NO_MATCH |
Character failed to match. |
curses(3X), menu(3X). |
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. |
