DISCUSSION

The URLGetPropertySize function obtains the size of a property in bytes. You should call URLGetPropertySize before calling URLGetProperty URLGetProperty to make sure the buffer you use when you call URLGetProperty is big enough to hold the property value. Pass the value returned in propertySize as a parameter to the URLGetProperty function.
