os_result dxd::memory< scope_t >::initialize ( const::MDL * mdl )

inlineinherited

in contrast to an IOKit MemoryDescriptor MDLs do not support reference counting. take care when creating a dxd::memory from a dxd::buffer: although the dxd::memory holds an MDL to the buffer the buffer itself is not retained after the dxd::buffer is released!
