Detailed Description

Utility class for exception-safe mutex locking.

Usage example:
{
Glib::Threads::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.
Deprecated:
Please use std::lock_guard or std::unique_lock instead.
