VMMInternal.h@ 23145

Last change on this file since 23145 was 23145, checked in by vboxsync, 15 years ago
VMM: Extended VMMR3EmtRendezvous with TYPE_ASCENDING, TYPE_DESCENDING and STOP_ON_ERROR for use with VM state changes. The return type of the callback was changed so that the callback can feed scheduling info to EM.
Property svn:eol-style set to `native` Property svn:keywords set to `Id`
