IIRC, these are member functions. So you'd call my_datatype.Commit() and my_datatype.Get_size(). > However, MPI::Datatype::Creat_struct(....) can be found. This is a static function that is just in the MPI namespace -- it is not a member function on an object instance. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
