Detailed Description

Atomic counter is a class that allows perform counting in thread safe way.

It is mainly used for reference counting. Under Windows it uses Interlocked API, under other platforms it used built-in atomic operations or fails back to pthreads locking implementation.

Notes:

• This counter is not safe for use in process shared memory, when pthreads fall-back is used
• Under POSIX platform pthread_mutex_t is always present in order to make sure that we can implement or remove pthread fall-back at any point not affecting ABI
