Re: boost::bind for member functions

Hi Bill, It's just a typo that's causing your problem: not_ok is declared like this:

int not_ok(const D *d, int j) { return d->d() + j; }

But the call to bind swaps the order of the 'const D*' and 'int' arguments:

Foo f2 = boost::bind(&B::not_ok, b, _1, d);

You want:

Foo f2 = boost::bind(&B::not_ok, b, d, _1);

Doh! It's not a typo, it's a major misunderstanding of the role of the _1. *Now* I get it.... Thanks!
