GraphEventFN is a pointer to a callback function for handling filter graph events. The application implements this callback function. The m_pVideo member variable provides a wrapper for the various DirectShow video renderers. See Step 2: Declare CVideoRenderer and Derived Classes. Throughout this...
When making a forward declaration to a function, the compiler has everything it needs in order to parse code which invokes that function: the name of the function, the type returned, the number of arguments, and the type of each argument. But when making a forward declaration to a class,...
