Hi guys,

Is there a way to make boost::function to be passed to a function required a pointer to a member function as parameter:

struct CFoo { int foo1(int){} int foo2(int, double){} };

int g(int (CFoo::*)(int));

int main() { g(&CFoo::foo1);

g(boost::bind(&CFoo::foo2, _1, _2, 666)); // Doesn't compile - boost::bind returns an object instead of function pointer

There is no way to fix this. g expects a pointer to member function of the class CFoo.

// The following doesn't compile - can't convert from int (*)(CFoo*, int) to int (CFoo::*)(int) g(boost::function( boost::bind(&CFoo::foo2, _1, _2, 666) ).target() ) }

I believe there are some compilers where you can do evil ugly hacks so that you can make a function taking a pointer to an object and n other arguments pretend to be a member function taking n arguments. Otherwise there is no solution but to change g.
