![]() And it's Asio decision when to execute your job (but of course it tries to do it as faster as possible =)). To better understand how it works, consider that every time you doing some boost::asio::async_ you are posting the pointer to data for operation and pointer to callback function to the job queue. The buffer has to be alive and socket opened during the whole transmition time (from asio::async_write call to handle_write callback is to be called by Asio io_service dispatcher. Your problem is all about lifetime of buffer and socket. So, I am guessing, not the entire string is written into the streambuf?Īlternatively, I would love to know what is the most elegant way to write using boost::asio::async_write, data that is larger than 65536 bytes!Īlex, you understand asio async operations wrong. However, although I get no errors, not the entire data is sent! I've tried using: boost::asio::streambuf _out_buffer Īs a class member, and then made method respond: std::ostream os( &_out_buffer ) So I am left with only one choice: To use a boost::asio::streambuf Typename Buffers::const_iterator begin_remainder_ usr/include/boost/asio/detail/consuming_buffers.hpp:261:36: error: no type named ‘const_iterator’ in ‘class boost::asio::mutable_buffer’ It seems like I can't use a boost::asio::mutable_buffer, but only a boost::asio::streambufįurthermore and more importantly, a second error complains about the actual boost::asio::async_write being passed a boost::asio::const_buffer OR boost::asio::mutable_buffer: /usr/include/boost/asio/detail/consuming_buffers.hpp:164:5: error: no type named ‘const_iterator’ in ‘class boost::asio::mutable_buffer’ Goes out of scope before the operation has a chance to finish sending all the data. Searching around Stack Overflow, I discovered that my problem is that the buffer created by the method: boost::asio::buffer( str ) Implying that the maximum buffer size (65536) was not enough to write the data? I know the problem is that boost::asio::async_write does not complete the writing operation, because the output from the above operations is: Reply bytesize: 354275 Std::cerr << "handle_write Bytes sent: " << bytes_transferred << std::endl Std::cerr << "handle_write Error: " << ssage() << std::endl ![]() Void handle_write ( const boost::system::error_code & error, size_t bytes_transferred ) Std::cout << "Reply bytesize " << bytes << std::endl īoost::asio::placeholders::bytes_transferred Std::size_t bytes = str.size() * sizeof( std::string::value_type ) If ( auto m = handleNewMessage( _message ) ) I have a very simple method, with the purpose of responding to an incoming message, and then closing the connection: void respond ( const std::string message )Ĭontroller & controller = Controller::Singleton() ![]()
