sync_ptr is a thread safe pointer. sync_ref_ptr is a reference counting (shared_ptr) derived version of sync_ptr sync_ptr and sync_ref_ptr can be used with Windows or UNIX/Linux via, WIN32 API's or POSIX functions. They can turn any object into a thread safe object. sync_ptr destructor will automatically destroy the object, so the object can be create via new on sync_ptr constructor. This insures no other process has ownership of the object.

Example Usage

sync_ptr<vector<int> > MyThreadSafeVectorInt(new vector<int>, new sync_ctrl_default);
cout << MyThreadSafeVectorInt->at(0) << endl;

An instance of RefLockPtr can be create to lock the object for the duration of a function.
Example Usage
sync_ptr<string> MyThreadSafeString(new string);

string SomeFunction()
sync_ptr<string>::RefLockPtr MyLockedString = MyThreadSafeString.get_locked_obj();
MyLockedString->operator=("Hello World");
return MyLockedString->substr(6);

The destructor for RefLockPtr automatically unlocks the object, so an explicit unlock call
is not required.
