Hello, For a server-client application, I am experimenting with boost::asio and boost::interprocess -- this is my first intensively boostified project. Since boost::interprocess is work-in-progress, I am using the CVS version. I have found some smaller problems (see at the end of my email), but so far, all works well. I have noticed that in interprocess, an ipc/named_fifo is planned. I was wondering if there will be plans for the asio library to create an asynchronous I/O service for such a fifo ? If not, is this feasible ? I did not find any documentation on how to write a new io_service in the asio documentation ? Regards, koen 1) Timeouts always timed out immediately, which was caused by : interprocess/sync/ptime_to_timespec.hpp line 29: ts.tv_sec = duration.seconds(); should be ts.tv_sec = duration.total_seconds(); 2) Compile problem in interprocess/errors.hpp, which was solved by : interprocess/errors.hpp line 86: void fill_system_message( int system_error, std::string &str) should be inline void fill_system_message( int system_error, std::string &str) (probably the same is true for the BOOST_WINDOWS versino on line 65 ?
