NTSTATUS TdiCopyBufferToMdl( IN PVOID SourceBuffer, IN ULONG SourceOffset, IN ULONG SourceBytesToCopy, IN PMDL DestinationMdlChain, IN ULONG DestinationOffset, IN PULONG BytesCopied ); Routine Description: This routine copies data described by the source buffer to the MDL chain described by the DestinationMdlChain. The Arguments: SourceBuffer - pointer to the source buffer SourceOffset - Number of bytes to skip in the source data. SourceBytesToCopy - number of bytes to copy from the source buffer DestinationMdlChain - Pointer to a chain of MDLs describing the destination buffers. DestinationOffset - Number of bytes to skip in the destination data. BytesCopied - Pointer to a longword where the actual number of bytes transferred will be returned. Return Value: NTSTATUS - status of operation.
