又想使用其他使用boost::system::error_code的boost库(例如boost ASIO)。
#include <boost/system/error_code.hpp> #include <boost/asio.hpp> #include <iostream> #include <string> int main() { boost::system::error_code ec; std::string hostname = boost::asio::ip::host_name(ec); std::cout << ec.value() << std::endl; } 下载源代码 Boost...
通过使用Boost库，可以在C++中方便地实现高精度数学运算，对于从事科学计算和数学建模等领域的人员来说，...
4. 操作系统向io_service返回执行结果. 5.io_service将错误的操作结果翻译为boost::system::error_code类型. error_code可与特定值进行比较,或作为boolean值检测(false表示无错误).结果再传递给IO对象. 6. 如果操作失败,IO对象抛出boost::system::system_error类型的异常.开始操作的代码如下所示: boost::system:...
boost::system::error_code ec; socket.connect(server_endpoint, ec); 而后error_code类型的变量ec被赋予操作的结果值,但不会抛出异常. 对于异步操作,事件顺序不同. 1.应用程序调用IO对象进行连接操作: socket.async_connect(server_endpoint, your_completion_handler); ...
