C2QueryOtherItems (

Routine Description:

    Function called to find out the current state of this configuration
        item. This function reads the current state of the item and
        sets the C2 Compliance flag and the Status string to reflect
        the current value of the configuration item.

Arguments:

    Pointer to the Dll data block passed as an LPARAM.

    INPUTS:

C2DisplayOtherItems (

/*++

Routine Description:

    Function called to display more information on the configuration
        item and provide the user with the option to change the current
        setting  (if appropriate). If the User "OK's" out of the UI,
        then the action code field in the DLL data block is set to the
        appropriate (and configuration item-specific) action code so the
        "Set" function can be called to perform the desired action. If
        the user Cancels out of the UI, then the Action code field is
        set to 0 (no action) and no action is performed.
