The trick is to read the declaration backwards (right-to-left):const int a = 1; // read as "a is an integer which is constant"int const a = 1; // read as "a is a constant integer"Both are the same thing. Therefore:a = 2; // Can't do because a is

歡迎閱讀此篇IOCP教程。我將先給出IOCP的定義然後給出它的實現方法,最後剖析一個Echo程式來為您撥開IOCP的謎雲,除去你心中對IOCP的煩惱。OK,但我不能保證你明白IOCP的一切,但我會盡我最大的努力。以下是我會在這篇文章中提到的相關技術:I/O連接埠同步/非同步堵塞/非堵塞服務端/用戶端多線程程式設計Winsock API
下載原始碼一、緒言 udp是一種面向非串連,不可靠的通訊協議,相對於tcp來說,雖然可靠性不及,但傳輸效率較高。所以在網路上仍有很大的用途。這幾日需要瞭解下udp通訊的過程,上網發現這方面的資料還挺少。於是仔細的翻找了下msdn,基本上搞清楚了udp通訊的過程。做了一個測試的例子。希望對大家有協助。二、udp的通訊過程server端: open a socket(socket)--->name the socket(bind)--->send and receive
