It's possible. Treat the __stdcall function as a function object and use the
general bind<R>(f, ...) syntax.
Here's an example from my code:
HWND get() const;
bool isDialogMessage(MSG * msg)
std::set<dialog *> const & instances = ::instances();
// see if the message is for a modeless dialog box
return std::find_if(instances.begin(), instances.end(),
boost::bind<BOOL>(::IsDialogMessage, boost::bind(&dialog::get, _1), msg)) !=
It would probably be an interesting extension to add the necessary __stdcall
overloads to bind but this is a dangerous path. :-)
