async_write是通过一次或者多次调用async_write_some函数来实现的,那么如果在第一个async_write还没有完成就调用第二个async_write,async_write_some就有可能先将第二个buffer的数据先发送出去。 因此,NEVER start your second async_write before the first has completed.
boost::asio::async_write() 是通过调用n次socket.async_write_some() 来实现的,所以代码必须确保在boost::asio::async_write()执行的时候,没有其他的写操作在同一socket上执行。 在调用boost::asio::async_write()的时候,如果指定buffer的length没有写完或出错,是不会回调相应的handler的,它将一直在run loop...

你要是看过basic_stream_socket的文档,里面提到async_write_some不能保证将所有要发送的数据都发出去。并且提到如果想这样做,需要使用boost asio的async_writehttp://www.boost.org/doc/libs/1_53_0/doc/html/b

Some stream implementations support queuing of write operations. In this case, the asynchronous execution of the WriteAsync method does not complete until the FlushAsync method has completed. For the buffer parameter, you don't have to implement the IBuffer interface. Instead, you can create an ...
