Matt Austern lists in his excellent book "Generic Programming and the STL" the functors select1st and select2nd for getting a pair's "first" and "second" members repsectively. His note to both says that they were in the original HP STL and in the SGI STL although they are not present in the current C++ Standard Library. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
