This works if you are on a fairly GNUy system. One that has GNUlibc,
such as a "linux" distribution. If this is the case then there should
be an info node called libc or glibc. If that is the case then just
pressing C-h S over a symbol documented in the manual should bring up
that symbols info-page.
Possible reasons why this doesn't work are:-
* Distribution does not set Info paths correctly
* Distribution does not ship with Glibc manual
If either of the above are the case then complain loudly.
This keystroke is C-h C-i in Emacs21 and C-h S in Emacs22.

It's not documented by Emacs, it's documented in the Info docs that
come with GLibc.

As other posters have said C-h S is better, the GNU info pages are
better than their man-pages.
