make_handle() Emil's handle.hpp creates a shared_ptr which points at a copy of the handle, whose lifetime is also controlled by the shared_ptr. So, you can access the handle through the shared_ptr as well as having the shared_ptr call the handle's cleanup function in its deleter. But my attempt at using lambda stores a pointer to the original handle in the shared_ptr, which becomes invalid as soon as the original handle goes out of scope.
Oh, and now I realize you are solving the problem by copying the handle into a void*. handle.hpp is still more useable though, since it could be used with any handle-like class, not just ints or similar that can copied into a void*. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFInEqJ5vihyNWuA4URAn+2AJ950uziyl/L8oWXKsj7pw4YzkN9VgCgxlSV 5ew6UUNQREACoYhF0kHLvRI= =L0TC -----END PGP SIGNATURE-----
