Detailed Description

Utility class for exception-safe mutex locking.

Usage example:
 {
   Glib::Mutex::Lock lock (mutex); // calls mutex.lock()
   do_something();
 } // the destructor calls mutex.unlock()
As you can see, the compiler takes care of the unlocking. This is not only exception safe but also much less error-prone. You could even return while still holding the lock and it will be released properly.
Examples:

thread/thread.cc.
