How it works...
Using the Resource Acquisition Is Initialization (RAII) C++ idiom, we can deine the
Lock
class:
class Lock
{
public:
explicit Lock( const clMutex* Mutex ) : FMutex( Mutex )
{ FMutex->Lock(); };
~Lock() { FMutex->Unlock(); };
private:
const Mutex* FMutex;
};
Then, using mutexes is straightforward:
Lock( &SomeMutex );
We use mutexes extensively almost everywhere in the subsequent chapters of this topic.

Managing memory using reference counting
When working in the native code environment, every memory allocation event is handled
by the developer. Tracking all the allocations in a multithreaded environment becomes
notoriously dificult. The C++ language provides a way to avoid manual object deallocation
using smart pointers. Since we are developing mobile applications, we cannot afford to use
the whole Boost library just to include smart pointers.
