GetCommandDescriptorBlock
Method to retrieve the SCSI Command Descriptor Block (CDB).
Declaration
bool GetCommandDescriptorBlock (
SCSIParallelTaskIdentifierparallelTask,
SCSICommandDescriptorBlock *cdbData );Parameters
- parallelTask:
A valid SCSIParallelTaskIdentifier.
- cdbData:
is a SCSICommandDescriptorBlock pointer to 16 byte CDB
Return Value
returns true if data was copied to cdbData pointer
Overview
This will always return a 16 Byte CDB. If the Protocol Layer driver does not support 16 Byte CDBs, it will have to create a local SCSICommandDescriptorBlock variable to get the CDB data and then transfer the needed bytes from there.
