Hi : I have this piece of code for mutex operations. is this code thread-safe ? I plan to use this code in threads... ------------------------------------ class BoostMutexLock { public : void lock() { lk = new boost::mutex::scoped_lock(global_mutex); } void unlock() { delete lk; } BoostMutexLock() : lk( 0 ) { } ~BoostMutexLock() { } private: boost::mutex global_mutex; boost::mutex::scoped_lock* lk; }; ------------------------------------------------------ I appreciate all the help.. How do I know to check for thread-safety in a code ? Are there any documents? I have checked online and have some links, but havent found documents which provide examples and explain.. such a document would be really useful. Thanks... Dhanvi
