P6UINT64 P6R::P6IOCONTEXT::m_cTransfer

When an I/O operation is posted, the number of bytes to read/write (or zero) is placed here.

If this is set to zero, the available buffer size (bufsize-used) will be automatically used. When the I/O operation completes, the number of bytes read/written will be placed into this element.
