![]() ![]() The DataTransferLength member of the SRB is updated when data is returned for the request function. The DataBufferOffset and DataBufferLength members of HYBRID_REQUEST_BLOCK are nonzero when data is returned for the specified Function. Output bufferĪn updated SRB_IO_CONTROL structure is returned to the data buffer in the SRB. Input buffer lengthÄataTransferLength indicates the size, in bytes, of the buffer, which must be at least sizeof (SRB_IO_CONTROL) + sizeof(HYBRID_REQUEST_BLOCK), with additional storage for function data if the DataBufferLength member of the HYBRID_REQUEST_BLOCK is nonzero. Depending on the Function member of HYBRID_REQUEST_BLOCK, additional data can be supplied. ![]() The buffer specified in the DataBuffer member of the SRB must contain an SRB_IO_CONTROL structure and a HYBRID_REQUEST_BLOCK structure. ![]()
