Last change on this file since 16303 was 16291, checked in by vboxsync, 16 years ago
NAT: multi threading. Introduces set of macroces to use locking/unlocking/creating/destroing mutexes Also every socket enqueueing is accomponement with lock creation (it doen't work yet, compilable on Windows don't know about Linux)
Property svn:eol-style set to `native`
