/*++

Routine Description:

    This routine translates the given FastIO code into a printable string which
    is returned.  

Arguments:

    FastIoCode - the FastIO code to translate
    FastioName - a buffer at least OPERATION_NAME_BUFFER_SIZE characters long
                 that receives the fastIO name.

Return Value:

    None.
