如何查找C结构的手册页（struct sockaddr_in）？

Question

I am having a hard time finding man pages for the structures used in socket. So I am currently learning about them from a separate online tutorial. But it would be nice to know how to lookup these structures in the man pages itself.

I am using a Debian 8.3 Linux system.

For example, I found information about struct addrinfo in man getaddrinfo .

But I have not been able to find information about struct sockaddr_in in any man page. Which man page contains the details about this struct? And how to find out the man pages for such structures in general?

Answer 1

You can find that specific structure by typing man 7 ip and then searching manually for it or pressing / and typing sockaddr_in .

If you don't know what section to look in you can try using a quick search with man -k sockaddr_in . If that doesn't give you the result you are looking for try brute-forcing it with man -K sockaddr_in , this might be very slow because it will scan all the man files on your system.

@Jean-FrançoisFabre his comment about using a search engine is probably the fastest way to find the information you want though.
