NAME¶
C++Intro - Introduction to the GNU libstdc++ man pages
DESCRIPTION¶
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.

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 leading
ext/ in the name. Otherwise you need to read FAQ 5.4.

Libraries¶
- libstdc++.a
- 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.
- libsupc++.a
- 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.
- libstdc++.so[.N]
- 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.
- libstdc++.la
- libsupc++.la
- These are Libtool library files, and should only be used
when working with that tool.
