[Description] File size is less than PAGE_SIZE. -or- InputBufferLength < sizeof(FSCTL_OFFLOAD_WRITE_INPUT). -or- One or more of these members of FSCTL_OFFLOAD_WRITE_INPUT are incorrect: FileOffset is not a multiple of the logical sector size of the volume. CopyLength is not a multiple of the logical sector size of the volume. TransferOffset is not a multiple of the logical sector size of the volume. Size is not the size of the FSCTL_OFFLOAD_WRITE_INPUT structure. FileOffset > Valid Data Length (VDL) for the file. FileOffset + CopyLength > MAXULONGLONG. [Return code]
