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 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).

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.
