C++Intro(3) Standard C++ Library C++Intro(3)NAME
C++Intro - Introduction to the GNU libstdc++ man pages
This man page serves as a brief introduction to the GNU implementation
of the Standard C++ Library. For a better introduction and more com‐
plete documentation, see the libstdc++ homepage listed at the end.
All standard library entities are declared within namespace std and
have manual entries beginning with "std::". For example, to see docu‐
mentation of the template class std::vector one would use "man
std::vector". Some entities do not have a separate man page; for those
see the main listing in "man Namespace_std".
All the man pages are automatically generated by Doxygen. For more
information on this tool, see the HTML counterpart to these man pages.
Some man pages do not correspond to individual classes or functions.
Rather they describe categories of the Standard Library. (For a more
thorough introduction to the various categories, consult a text such as
Josuttis' or Austern's.) These category pages are:
C++Intro This page.
Namespace_std A listing of the contents of std::.
Namespace___gnu_cxx A listing of the contents of __gnu_cxx::.
Containers An introduction to container classes.
Sequences Linear containers.
Assoc_containers Key-based containers.
Iterator_types Programatically distinguishing iterators/pointers.
Intro_functors An introduction to function objects, or functors.
Arithmetic_functors Functors for basic math.
Binder_functors Functors which "remember" an argument.
Comparison_functors Functors wrapping built-in comparisons.
Func_ptr_functors Functors for use with pointers to functions.
Logical_functors Functors wrapping the Boolean operations.
Member_ptr_functor Functors for use with pointers to members.
Negation_functors Functors which negate their contents.
SGIextensions A list of the extensions from the SGI STL subset.
The HTML documentation typically goes into much more depth.

For GCC 3.0 these headers will be found automatically, unless you
instruct the compiler otherwise. You should not depend on this,
instead you should read FAQ 5.4 and use a backward/ prefix.
These headers will only be found automatically if you include the lead‐
ing ext/ in the name. Otherwise you need to read FAQ 5.4.
The library implementation in static archive form. If you did
not configure libstdc++ to use shared libraries, this will
always be used. Otherwise it will only be used if the user
This library contains C++ language support routines. Usually
you will never need to know about it, but it can be useful. See
The library implementation in shared object form. This will be
used in preference to the static archive form by default. N
will be a number equal to or greater than 3. If N is in the 2.x
series, then you are looking at the old libstdc++-v2 library,
which we do not maintain.
These are Libtool library files, and should only be used when
working with that tool.
