Dear all, i am new to threading. i want to know the following. Given a shared object which is accessed by more than one process, where should we implement the mutex locking? Is it in the shared object or in the critical section of the Processes? If locking is done in process, will it work having different names for the locks in the processes? class A { .......... ........ public: execute() { ......... lock(mutex1) //write data to shared object unlock(mutex1) ......... } }; class B { .......... ........ public: execute() { ......... lock(mutex2) //write data to shared object unlock(mutex2) ......... } }; SharedObject { ........... .......... }; -- Wesley K

you lock where the data is being accessed.

I'm not sure what you mean. You might also want to take a look at this article: http://www.ddj.us/cpp/211600441?pgno=3 -- alfonso e. urdaneta _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ This e-mail and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
