C++ (Cpp) SimpleMutex::lock Examples

Example #1

File: LintelLog.cpp Project: dataseries/Lintel

void LintelLog::maybeInitInstance() {
    static SimpleMutex init_mutex;

    // is this actually safe?  Really don't want to have to take the
    // lock when we almost never need to.
    if (instance == NULL) {
	init_mutex.lock();
	if (instance == NULL) {
	    instance_data *tmp = new instance_data();
	    tmp->mutex.lock(); // try to force the above to be 
	    tmp->mutex.unlock();
	    instance = tmp;
	}
	init_mutex.unlock();
    }
}

Example #2

File: mmap_win.cpp Project: MStumpp/mongo

 RemapLock::RemapLock() {
     _remapLock.lock();
 }

Example #3

File: mutex.cpp Project: nefthon/Source

{
	mutex.lock();
}
