QuercusVL Programming Manual3.20.2. Methods● IsValidC++: bool IsValid()C: Does not existReturns true if the object contains valid information about a real time event, and false ifinvalid. Some methods, may sometimes, return void real time events. In C, thisbehaviour is detected as its value will be “0”. In C++, however, this method isnecessary because the object, as it is not a pointer, would always be valid.● AddRefC++: Does not existC: void VL_RealTimeInformation_AddRef ( int h )Ver 2.2.1.
