#include <boost/bind.hpp> ... int updateVal; ... for_each(blocks.begin(), blocks.end(), boost::bind(&Block::update, _1, updateVal)); Jeff -----Original Message----- From: Mark Snelling [mailto:mark@bakedbeans.com] Sent: Wednesday, September 04, 2002 10:17 AM To: Boost-Users@yahoogroups.com Subject: [Boost-Users] Newbie boost::mem_fn problem Hello, My problem I think is very simple, I just can't seem to find the solution I have an STL list of object pointers and I want to call a member function on each of the pointers in the list usigng the STL for_each algorithm. This would seem easy if the list contained the actual objects rather than pointers to them, but because they are pointers I can't find a way of doing this. class Block { public: void update(int x); }; void main() { list<Block*> blocks; for_each(blocks.begin(), blocks.end(), *****); // Call update on each item in list } what should I replace the ***** with? Any help appreciated! Mark.
