The new buffer to or from data will be transferred.
Returns kIOReturnSuccess on success. Will return an error if the range specified by [buffer, buffer+size] is not in the range of memory locked down for this program.

The buffer can be set to be any location within the range of buffers specified when the DCL program was compiled (including 0). Availability: IOFireWireLocalIsochPortInterface_v3 and newer.
