"function call missing argument list; use '&function' to create a pointer to member"

[NMTop40]

double f( void * z )
{
   CMultilatera * pMultilatera = static_cast< CMultilatera * >( z );

   pMultilatera->memberFxn();
}

If it's necessary to do this in a C++ application then I would say that you're design is seriously flawed!

Why can't you do this?

double f( CMultilatera &z)
{
   z.memberFxn();
}

You would do the above so you can pass f to a C API for example as a thread function (although they don't normally return double).
