Suppose we have a shared queue (implemented using an array), which two threads can access, one for reading data from it, and other for writing data to it. Now, I have a problem of synchronization. I'm implementing this using Win32 API's (EnterCriticalSection etc.).
But my curiosity is what will be the critical section code in enqueue and dequeue operations of the queue?
Just because, two threads are using a shared resource? Why I'm not able to see any problem is this: front and rear are maintained, so, when ReaderThread reads, it can read from front end and when WriterThread writes, it can easily write to rear end.
What potential problems can occur?
