Category: Threads and Synchronization

In a multithreaded environment, each thread has its own local thread stack and registers. If multiple threads access the same resource for read and write, the value may not be the correct value. For example, let’s say our application contains two threads, one thread for reading content from the file and another thread writing the content to the file. If the write thread tries to write and the read thread tries to read the same data, the data might become corrupted. In this situation, we want to lock the file access. The thread synchronization has two stages. Signaled and non-signaled.
