Can you change the function signature to allow you alloc and pass the buffer to the function… then management is all yours.

The functions return wchar_t* which I marshal into a managed string. The author of the C++ code doesn't know when to free the buffer he's allocated for the string (neither do I). The very last statement in his function is return char_ptr, so the function ends and the buffer becomes a leak. I consume the pointer after his function ends, so when can he delete it? Is there some trick I'm forgetting? Or are we doing it the wrong way? Greg K
