Re: Locking Resources

hi, may be this is not the right place to ask this question.
In my MFC application i need to lock a resource, i dont now what kind of mechanism to use exactly in microsoft environment .

Let the resource be a STL vector. this is a shared vector in a multithreaded application.

i need somehting like;
<code>

mutex.lock()
  // vector operations ..
mutex.unlock()

</code>

each thread thats wants to access this vector must sleep if resource is locked.

Best Regards...



MFC provides CCriticalSection for this, but its design and documentation are obscure. I suggest the simpler Win32 CRITICAL_SECTION object. Initialize the object with InitializeCriticalSection, then do this in each thread that accesses the shared data...

EnterCriticalSection(&cs);
   // vector operations ..
LeaveCriticalSection(&cs);
