Is there any problem with using shared_ptr and passing an instance of it to a function in another shared library, such as a DLL under Windows ? Does the reference count get updated correctly when the copy is passed to a DLL function, so that when the last shared_ptr in either the original module or the DLL goers out of scope, the actual pointer is correctly deleted ? I've been using it successfully across DLL boundaries with no problems.
The biggest caveat is to ensure you are using the DLL version of the C Runtime library. If you use the static library version, then each DLL will have its own heap, and a pointer *must* be deallocated in the same DLL in which it was allocated. -- Jim Hyslop Senior Software Designer Leitch Technology International Inc.
