问题描述
是否有如何阅读和使用C解析二进制数据？任何库或指南
Are there any libraries or guides for how to read and parse binary data in C?
我在看一些功能，将网络套接字接收TCP数据包，然后根据规范解析二进制数据，由code转动信息融入了更多可用的形式。
I am looking at some functionality that will receive TCP packets on a network socket and then parse that binary data according to a specification, turning the information into a more useable form by the code.
有没有做到这一点的所有库在那里，甚至在执行这种类型的事情底漆？
Are there any libraries out there that do this, or even a primer on performing this type of thing?
推荐答案
标准方式C / C ++是真正铸造结构为gwaredd建议这样做。
The standard way to do this in C/C++ is really casting to structs as 'gwaredd' suggested
这并不像人们想象的那么不安全。你先投给你意料之中的，因为在他/她的例子结构，，然后您测试结构的有效性。你要测试的最大/最小值，终止序列等。
It is not as unsafe as one would think. You first cast to the struct that you expected, as in his/her example, then you test that struct for validity. You have to test for max/min values, termination sequences, etc.

什么都你的平台上，你必须阅读。买吧，借用它，窃取它（受害者就会明白，这就像偷菜什么的...），但不要读它。
What ever platform you are on you must read Unix Network Programming, Volume 1: The Sockets Networking API. Buy it, borrow it, steal it ( the victim will understand, it's like stealing food or something... ), but do read it.
阅读史蒂文斯后，大部分的这将使很多更有意义。
After reading the Stevens, most of this will make a lot more sense.
