service process, each managed object reference is simply a small data structure, containing a COM pointer to the “real” COM object, the web session ID and the object ID. This structure is allocated on creation VirtualBox version dependent header file name and makes sure the global variable g_pVBoxFuncs contains a pointer to the structure which contains the helper function pointers. Here’s how to initialize the C API: library, handles errors * (producing an error message hinting what went wrong) and gives you * the pointer to the function table (g_pVBoxFuncs). * * Once you get the function table, then how and which functions
