A protocol was specified in the socket function call that does not support the semantics of the socket type requested. 在套接字函数调用中指定的一个协议不支持请求的套接字类型的语法。
From a control-flow perspective, an event is a function call, whereas an exception is a long jump across the stack, with unwinding semantics to destroy lost objects. 从控制流的角度看,事件是一次函数调用,而异常则是堆栈的突然跳跃,用展开的语义销毁丢失的对象。
