Hi all,

I am new to device driver programming. I am trying to access the BCA portion of the DVD using C++. I have tried using IOCTL_DVD_READ_STRUCTURE with DVD_LAYER_DESCRIPTOR, DVD_BCA_DESCRIPTOR. Other than above i have tried using IOCTL_SCSI_PASS_THROUGH with buffers. I dont understand where is the BCAFlag i.e., which byte, from what offset the flag value is represented in the DVD. It would be greatful if i get a lead in this problem. using scsi pass through with buffers what is SenseInfoLength, DataTransferLength, TimeOutValue, SenseInfoOffset values to be used?
CDB to be passed a in paramter to DeviceIoControl api.
