Detailed Description

A handy interface to protect critical sections.

This exploits the way how the C++ compiler automatically creates constructor and destructor calls in the code, especially when the scope in which an object was declared is left.

So if you enter a critical section using its constructor and leave it again in the destructor, you can easily mark critical code areas as follows:

// non-critical section
...
{
Guarded section;
// critical section
...
}
// non-critical section
