Well, in DLL/DSO you can track loads unloads using some global variables:
I think he meant that he wants the ability to hook into the load/unload of some arbitrary DLL/DSO, so like a DLL/DSO local atexit() as it were. This is trivial to implement, simply a static object defined per DLL/DSO which accepts a list of bound functions to call when it gets destructed. Something kinda cool would be combining that hook with the pointer-to-DLL/DSO code I sent you, so you could have code like: // Tell me when the DLL/DSO owning this string gets unloaded so I can // delete my use of it dll_from_ptr(str)->on_unload(std::bind(this, &remove_string, str)); Niall -- ned Productions Limited Consulting http://www.nedproductions.biz/ http://ie.linkedin.com/in/nialldouglas/
