Hi Peter,
copy_if(istream_iterator<Terminal>(cin), istream_iterator<Terminal>(), back_inserter(temp), compose2(equal<set<Terminal>::iterator>(), bind1st(bind1st_3(ptr_fun(f), V_.begin()), V_.end()), V_.end())));
(I've prepared any goodie needed by ternary functions for the above statement: ptr_fun, bind1st_3, ...)
Dev-C++ 4.9.8.0 (GCC 3.3.2 I think), gives me several errors (including "Reference to Reference" problem), and I'm nearly convinced not to continue it this way.
Now, how do you, boost guys, do that?
You probably need
boost::bind(equal<set<Terminal>::iterator>(), boost::bind(f, V_.begin(), V_.end(), _1), V_.end() )
Hmmm..., this is not exactly what I meant. But you made me to search in the Boost for bind, and I found what I wanted. Thanks again, --Hossein __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free web site building tool. Try it! http://webhosting.yahoo.com/ps/sb/
