VirtualBox

source: vbox/trunk/src/VBox/Main/HostDVDDriveImpl.cpp@ 3090

Last change on this file since 3090 was 3007, checked in by vboxsync, 18 years ago

Moved the template code out of cdefs.h, partly because it didn't belong there but mostly because it was at the end of the file and would screw up any attempts made by the object cache at avoid recompiling on cdefs.h changes.
