It won't compile because that file does not exist. It sounds like you should get a new cppcookbook, given the number of examples you've posted about that are broken. You should probably first try emailing the author of that book regarding these problems. I believe you're looking for a shared_mutex.

The code is wrong, and we cannot divine the original author's intent. I suggest you contact the author regarding their broken code. Brian

Dear boost programers:  http://examples.oreilly.com/9780596007614/   12-3.cpp   is the program I am talking about.   although I will try to contact authors(4                D.Ryan Stephens                Christopher Diggins                Jonathan Turkanis                Jeff Cogswell                , and I can only find email of second one, and I emailed him but never get him reply) hope boost experts/programers take care on this problem a little bit more deeper and like to see your post again to make this problem be fixed someway.   Eric  

Looking at the SVN logs, read_write_mutex.hpp was removed from Boost on 5 Oct 2007 (revision 39693.)  The only release I can find on SourceForge that contains this file is 1.34 Beta (http://sourceforge.net/projects/boost/files/boost/1.34.0%20Beta/).  My guess would be to compile your code against that release. According to a comment on revision 39891, "read_write_mutex makes a comeback --- as shared_mutex."
