Is there a good online reference for C++ libraries?

[lars.uffmann]

Okay, I guess the answer is "yes". But where can I find it?
I was thinking of something like php.net, just for c++. Preferably some
documentation that refers to the same standards that the gnu c++
compiler does (I'm using g++ V3.3.5 under Suse Linux 9.3).

In this specific case I wanna know the easiest way how to convert an
integer into a string variable (I mean which library / function to
use). I'm not a programming newbie by any means, but getting used to a
new developing environment sorta makes me feel like one all over again,
when I suddenly have to work without an extensive language reference
within my favourite editor and the likes...

I'm pretty happy with the way I can look up things on php.net, for php
- if there's anything similar for C++, I'd be overjoyed if you could
share the info

I like parashift.com, but is this:

http://www.parashift.com/c++-faq-lite/misc-technical-issues.html#faq-39.1
really the best way to do what otherwise could be a simple "alpha" << i
to make a string "alpha5" from i=5 ?

I often use this online reference: http://www.dinkumware.com/refxcpp.html

I also recommend this hard copy book: www.josuttis.com/libbook

You'll need to decide what 'best' means to you. It might
not mean the same to others.

Google for 'boost::lexical_cast<>'. Then get a simple version that works,
not the eternally correct and un-borrow-able one at www.boost.org

That's the problem with C++ - we invented it before HTML, so it has no root
webpage or single controlling entity. So all the rules, guidelines, tricks,
and traps are scattered hither and yon.

My favorite site is: <http://www.sgi.com/tech/stl/> for the stl stuff.
For everything else I just do a google search on the header name. Try

That's what it takes. You need to use a stream of some sort to convert
the integer into a string, and you need to format it properly if the
default isn't satisfactory.

"we invented it" ... ??? I certainly had no part in it. It would be
interesting to hear what you did to help Bjarne Stroustrup back in
those days!

No, but the C++ FAQ Lite contains many other useful and
understandable(!) tips. I'd write a function that internally uses
snprintf.
