Efficient way to browse header definitions

As an example: on my system (Ubuntu 10.04), the sockaddr structure is defined in /bits/sockaddr.h as

struct sockaddr{
   开发者_运维技巧 _SOCKADDR_COMMON (sa_); /*...*/
    char sa_data[14];  /*...*/
};

and similarly for sockaddr_in, with first field name sin_.

However, all the examples I see access the field sin_

structure_name.sin_family

I meant to track down the typedef (?) for completeness, followed included headers and such, but failed (I got to sa_family_t and similar).

As a more general question: is there, say, a searchable online source where you can simply search for where a macro or typedef is in the header files - either for a particular Ubuntu distribution, or more generically for 'typical' Linux installations? Or, obviously, a clever way from within Ubuntu's shell; or some description of how to be more efficient doing this any other idea.

LXR / The Linux Cross Reference

done...i'll get you the reference for the Linux Kernel API Browser later (used to be able to find it online somewhere). There's the Linux Kernel Archives for the actual source code, which you probably could generate documentation from anyways.

Sorry, but I've not come across something as beautiful as say, the jQuery API Browser. Hopefully the 'Ubuntu Manpage' @ manpages.ubuntu.com/manpages/lucid/man7/netdevice.7.html, for example, might suffice. Also for stuff like the struct sockaddr{, you might like to check out the Linux Kernel API Browser (or something similar) as that belongs to standard Linux networking protocol headers.
