Is the documentation for Boost::Bind matching the std::tr1::bind that got accepted?  That is, can I read this to understand it since the docs are better than what comes with the compiler, or are there differences?

Consider a member function C::foo.  If I want to bind the object this parameter but leave the rest unchanged, would bind(&C::foo,x) automatically give me bind(&C::foo,x,_1,_2,_3)?  

What if I want to call x->foo(5,_3) and not use the first two parameters or the 4th, to make something that is passed to a callback function that wants 4 arguments?  That is, the callback F is invoked F(a,b,c,d) and I want to make a function instance that can be assigned to F, and ends up calling x->foo(5,c).
