即使Boost.Asio可以异步处理任何类型的数据，它也主要用于网络编程。 这是因为Boost.Asio在添加了其他I /...
Boost.Asio may use one or more hidden threads to emulate asynchronous functionality(async_resolve()就会创建额外的内部线程来执行). The above requirements are intended to prevent these hidden threads from making calls to program code. This means that a program can, for example, use thread-unsafe r...

发送数据也使用了异步方式(async_write_some), 同样要保证在整个异步发送期间缓冲区的有效性,所以也用boost::bind绑定了boost::shared_ptr。 对于客户端也一样,在connect和read_some方法前加一个async_前缀,然后加入回调即可,大家自己练习写一写。 ASIO的“便民措施” ...
动手呗, async_read_until看似就是一个废柴, 底层已经费了很多CPU在逐字符与分隔符的匹配上, 抛上来的数据居然还是半成品. 代码如下, 测试通过, 但是实在很费解为啥非要再做一次.. boost::asio::streambuf* SB = SBP.get();// 访问缓冲constchar* Buffs = boost::asio::buffer_cast<constchar*>( SB-...
当然你可以使用 boost::asio::io_service::strand让完成事件处理器的调用,在同一时间只有一个, 比如下面的的代码: socket_.async_read_some(boost::asio::buffer(buffer_), strand_.wrap( boost::bind(&connection::handle_read, shared_from_this(), ...
