Miscellaneous

- clearMemoryDescriptor

Clears the DMACommand's current memory descriptor

- cloneCommand

Creates a new command based on the specification of the current one.

- complete

Complete processing of DMA mappings after an I/O transfer is finished.

- gen32IOVMSegments

Helper function for a type checked call to genIOVMSegments(qv), for use with an IODMACommand set up with the output function kIODMACommandOutputHost32, kIODMACommandOutputBig32, or kIODMACommandOutputLittle32. If the output function of the IODMACommand is not a 32 bit function, results will be incorrect.

- gen64IOVMSegments

Helper function for a type checked call to genIOVMSegments(qv), for use with an IODMACommand set up with the output function kIODMACommandOutputHost64, kIODMACommandOutputBig64, or kIODMACommandOutputLittle64. If the output function of the IODMACommand is not a 64 bit function, results will be incorrect.
