       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
       complete 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
       documentation 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.


   Standard Headers
       These headers will be found automatically, unless you instruct the
       compiler otherwise.

       <algorithm>  <csignal>     <iomanip>   <ostream>
       <bitset>     <cstdarg>     <ios>       <queue>
       <cassert>    <cstddef>     <iosfwd>    <set>
       <cctype>     <cstdio>      <iostream>  <sstream>
       <cerrno>     <cstdlib>     <istream>   <stack>
       <cfloat>     <cstring>     <iterator>  <stdexcept>
       <ciso>646    <ctime>       <limits>    <streambuf>
       <climits>    <cwchar>      <list>      <string>
       <clocale>    <cwctype>     <locale>    <utility>
       <cmath>      <deque>       <map>       <valarray>
       <complex>    <fstream>     <memory>    <vector>
       <csetjmp>    <functional>  <numeric>

   Backwards-Compatibility Headers
       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.


   Extension Headers
       These headers will only be found automatically if you include the
       leading ext/ in the name.  Otherwise you need to read FAQ 5.4.

       <ext/algorithm>            <ext/numeric>
       <ext/functional>           <ext/iterator>
       <ext/slist>                <ext/rb_tree>
       <ext/rope>                 <ext/memory>
       <ext/bitmap_allocator.h>   <ext/debug_allocator.h>
       <ext/malloc_allocator.h>   <ext/mt_allocator.h>
       <ext/pool_allocator.h>     <ext/pod_char_traits.h>
       <ext/stdio_filebuf.h>      <ext/stdio_sync_filebuf.h>

              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
              requests it.

              This library contains C++ language support routines.  Usually
              you will never need to know about it, but it can be useful.  See
              FAQ 2.5.

              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.
