    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.
    E_NOT_CONNECTED
    No items are connected to menu.
    E_NO_MATCH
    Character failed to match.
    E_SYSTEM_ERROR
    System error occurred (see errno).
     

    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.
