ok, well strictly C++ has no concept of a library and no such concept as dlopen(). I do always export objects rather than functions because casting void* to a function pointer is undefined behaviour, in fact a function pointer might not fit into void* and doesn't on some systems (void* can often be 32-bit while function pointers are 64-bit). dynamic_cast is part of C++ standard. It does have its uses, in fact plug-ins is the only time I ever use it. That is because you receive an object and want to verify it is the type you expected so if it isn't you can handle the error cleanly (by throwing an exception) rather than invoking undefined behaviour (as would occur with any other type of cast if you then called member functions on it). _______________________________________________ help-gplusplus mailing list help-gplusplus@gnu.org http://lists.gnu.org/mailman/listinfo/help-gplusplus
