ReadWrite Mutex

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.

This Qt Solutions component is for Qt 3. For Qt 4 Solutions, please visit the Qt 4 Solutions Catalog.
