Where to find function reference for gcc?

[yeskw]

I am looking for the function reference,
but I can't get it in the "on line document" page.
Would you can tell me where to find it?
Thank you.

Here is the version of gcc:
$ gcc -v
Using built-in specs.
Configured with: FreeBSD/i386 system compiler
Thread model: posix
gcc version 3.2.2 [FreeBSD] 20030205 (release)
