Re: [Boost-users] boost & c-style calback issue

void do_something(foobar cb); // this function accepts argument which is a point of function do_something(obj); // but obj is a function. i think we should do it like tihs class A { }; class B { }; class C { public: int operator () (A*,B*){ cout<<"yes"<:

Hi,

i'm facing this problem may be someone on the list do have an elegant solution

class A; class B;

class C { int operator () (A*,B*) };

typedef int (*foobar)(A*,B*); void do_something(foobar cb);

C obj; do_something(obj); *ERROR*

did try boost::function ftor = obj; do_something(ftor); *ERROR*

compiler generates in both cases the following error messages cannot convert parameter 2 from 'boost::function<Signature>' to 'int (__cdecl *)(A *,B *)'

with 1> [ 1> Signature=int (A *, B *) 1> ] 1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

I can't make the corresponding class B member function static due to side-effects. Any clue how to get rid of this?

Thanks in advance Mike
