Hello Michael,
*this is a pointer to the mutex that the 'lock_guard' is using. The name "this" is unfortunate since it overlaps with an object's 'this' pointer... unless your class 'mytype' is derived from a mutex....
I believe just what I'm looking for. From a previous reply, I don't "really" want to derive from lockable classes, I just want to guard this class as a potentially thread-safe operation.
I've usually seen it used on just a boost::mutex.
boost::mutex the_lock;
and later in some code associated with the lock, you could activate it in a block by doing;
boost::lock_guardboost::mutex lock(the_lock); ...do stuff....
Consider looking at: http://www.boost.org/doc/libs/1_53_0/doc/html/thread/synchronization.html#th... searching for lock_guard I think it has a pretty decent example there.

Hello,
The pattern goes something like this: boost::lock_guard<mytype> guard(*this).
However, compiler is asking for a lock or unlock. I don't know what this is, or what it should be.
Thank you...

Michael Powell
