Hello: I just started using some boost today. I am trying to use a non-static member function as the deleter in a shared_ptr. I was looking at the source code and I don't think it is supported. This is what I had: shared_ptr<Environment> environment(Environment::createEnvironment(), Environment::terminateEnvironment); string userName = "monkey_bottoms"; string password = "blahblahblah" shared_ptr<Connection> connection( environment->createConnection( userName, password), &Environment::terminateConnection); This didn't work at all! When I looked at the source I saw why. Note that Environment::terminateConnection is a static method. However, this source works fine for the static Environment::createEnvironment method. I am working in Visual Studio 8 with the OCCI. For the time being, I have made a temporary solution. I am hoping someone can help me find a less customized solution. Plus, I am thinking having a pointer to an object that I am trying to manage kind of defeats the point. Here you go: #include "occi.h" #include <boost/shared_ptr.hpp> #include <string> #include <functional> // retarded temporary solution template <class TCLASS, class TRETURN, class TARG> class call_redirect_t : public std::unary_function<TARG, TRETURN> { TCLASS * instance; // barf I have a pointer to a managed resource! TRETURN (TCLASS::*func) (TARG); public: call_redirect_t(TCLASS * instance, TRETURN (TCLASS::*func) (TARG)) : instance(instance), func(func) { } TRETURN operator()(TARG arg) { return (instance->*func)(arg); } }; // convenience function template <class TCLASS, class TRETURN, class TARG> call_redirect_t<TCLASS, TRETURN, TARG> call_redirect(TCLASS * instance, TRETURN (TCLASS::*func)(TARG)) { return call_redirect_t<TCLASS, TRETURN, TARG>(instance, func); } int main(int argc, char * argv[]) { // lazy using namespace std; using namespace oracle::occi; using namespace boost; shared_ptr<Environment> environment( Environment::createEnvironment(), // gets Environment * Environment::terminateEnvironment); // static method string userName = "flipflop"; string password = "memoryrizor"; shared_ptr<Connection> connection( environment->createConnection(userName, password), // gets Connection * call_redirect( environment.get(), // pull the pointer out; instant poo &Environment::terminateConnection) // non-static method ); } Well, now that I think about it; since the temporary call_redirect will only exist in the scope of the shared_ptr (who handles my resource) it doesn't matter that I let it go, and parameter evaluation order is not an issue. Take a look at the operator() in call_redirect_t. I had to put parenthesis around: (instance->*func) I am think I have forgotten the syntax. Hmph. Weep, I am not perfect. Thanks for any input, folks.
