ReadWrite Mutex

Description

The QtReadWriteMutex class is useful to synchronize multithreaded access to resources that can support multiple readers, but only one writer.

This class can be used by multi-threaded applications to synchronize read and write access to resources that are shared between threads. It will allow write access to only one thread at a time, and ensure that no threads have read access while the resource is being written to. It can also be used to limit the number of simultaneous reading threads.
