Windows收集編程之winsock完成文件傳輸示例

編輯:關於C++

Windows收集編程之winsock完成文件傳輸示例。本站提示廣大學習愛好者:(Windows收集編程之winsock完成文件傳輸示例)文章只能為提供參考,不一定能成為您想要的結果。以下是Windows收集編程之winsock完成文件傳輸示例正文


本文實例展現了Windows收集編程中winsock完成文件傳輸的辦法,關於停止Windows下的winsock收集編程有必定的自創參考價值。

該法式代碼重要是基於TCP流協定的winsock收集文件傳輸示例,采取Windows下的C說話編寫。可以完成傳遞任何格局文件的文件傳輸功效。

詳細完成代碼以下:

Server端代碼以下:
