Routine Description:

    This routine translates the given Irp codes into printable strings which
    are returned.  This guarantees to routine valid strings in each buffer.
    The MinorCode string may be a NULL string (not a null pointer).

Arguments:

    MajorCode - the IRP Major code of the operation
    MinorCode - the IRP Minor code of the operation
    FsctlCode - if this is an IRP_MJ_FILE_SYSTEM_CONTROL/IRP_MN_USER_FS_REQUEST
                operation then this is the FSCTL code whose name is also
                translated.  This name is returned as part of the MinorCode
                string.
    MajorCodeName - a string buffer at least OPERATION_NAME_BUFFER_SIZE
                characters long that receives the major code name.
    MinorCodeName - a string buffer at least OPERATION_NAME_BUFFER_SIZE
                characters long that receives the minor/fsctl code name.

Return Value:

    None.
