Couldn't you use lambda for this?

boost::shared_ptr<int> s;
{
  int sockfd = socket(PF_INET,SOCK_STREAM,0);
  if( sockfd!=-1 )
    s.reset(&sockfd, boost::lambda::bind(close, * boost::lambda::_1));
}

I've never really used lambda, but it compiles at least.  By the way, is there 
any documentation on the lambda headers (which ones to include to use what)?  
I didn't see anything in the lambda docs.
