Is there a marshaling library in boost and is there an interest in such a functionality? Is the serializing library any use to marshall calls? I've not seen any mails concerning marshaling recently, though I might have missed one. Thanks, Hans I'm thinking something along the lines of the following. Although it may not be possible, I think it is (maybe the function registry is not necessary). int func( int i, int j ) { using namespace std; cout << "i: " << i << " j:" << k << endl; return i + j; } int main() { using m = boost::marshall; using std; int funcid = 1; m::register_function( funcid, func ); // Using same principles as in boost::function for type safety. m::call x(funcid, 1, 2); string str = x.serialize(); m::call y( str ); try { cout << y() << endl; } catch( m::invalid_function x ) { cout << x.what() << endl; } return 0; } // ------ // Should output: // i: 1 j: 2 // 3
