Constructs a CRtdLink object
CRtdLink( size_t maxThreads = 4, const TCHAR* waitMessage = _T("") );
The maximum number of threads that will be used by for asynchronous functions.
If the value is 0 then an exception of type CXlOutOfRangeException will be thrown.
The string that will be returned by all incomplete asynchronous functions.
If the value is blank then a default value will be used. This is "#WAIT!" in English and a similar value in other supported run-time languages.
The parameter values passed to this constructor will be applied to the CRtdAsyncManager object owned by the base class.
