c - 理解套接字 - c

Question

我正在尝试了解更多套接字。所以我在头文件socket.h中，在sys库中找到了一些函数声明bind(), connect()，但是我没有找到它们的定义？我在哪里可以找到它？

告诉我这个问题是否不相关，我将把它移到别处

Answer 1

You're really suggested to read Beej's guide to network programming to make sense of these functions. Manpages (-S2) will help too.

The source code of the function (if that's what you hope to find) won't help a lot. They call system calls to do their job, as they're mostly OS-abstraction layer. What you need is their documentation.

Answer 2

我建议您查看http://www.linuxhowtos.org/C_C++/socket.htm以了解有关套接字的更多信息。

Answer 3

您不会在标题中找到它们的定义，您需要深入了解您的 libc。但是你也不会在那里找到任何真正有用的东西，因为那些是系统调用，所以你真的需要挖掘你的内核。
