NAME
menu_pattern - get and set a menu's pattern buffer
SYNOPSIS
#include <menu.h>
int set_menu_pattern(MENU *menu, char *pattern);
char *menu_pattern(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 decribed 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 maty return the following error codes:
5 E_OK The routine succeeded.
5 E_SYSTEM_ERROR System error occurred (see errno).
5 E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument.
5 E_NO_MATCH Character failed to match.
SEE ALSO
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.
