C++Intro(3)

💖 C++Intro 💖

okay bestie, welcome to C++Intro from the Standard C++ Library — this is your little doorway into the GNU libstdc++ man pages 🫶

---

✨ NAME ✨

C++Intro — a whole intro to the GNU libstdc++ man pages, fr fr 💅

---

🌸 DESCRIPTION 🌸

So this man page is basically the welcome mat for the GNU implementation of the Standard C++ Library. It's short on purpose. If you want a real intro and the full tea, go check the libstdc++ homepage — it's linked at the bottom, iykyk ✨

Every single standard library entity lives inside namespace std, and its man page starts with "std::". Like, if you wanna read up on the template class std::vector, you literally just type:

man std::vector

Iconic. But heads up — some entities don't have their own separate man page, and for those you gotta go look at the big listing in man Namespace_std. No cap. 🙈

Also, every one of these man pages is automatically generated by Doxygen. If you wanna know more about that tool, peep the HTML counterpart to these man pages. 🎀

And some man pages aren't about one single class or function at all — they're describing whole categories of the Standard Library. (If you want a way more thorough intro to all these categories, go read a text like Josuttis' or Austern's. That's the homework, bestie. 📚) These category pages are:

• C++Intro — this page. hiii that's us 🫶
• 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. So if you're a details girlie, that's your lane. 💜

📁 FILES 📁

Lots! 😭 (yes that's the whole answer, she's mysterious)

🍓 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. But do NOT depend on this — instead you should read FAQ 5.4 and use a backward/ prefix. that's the rule, periodt 💅

<strstream>

🧚 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>

🌈 Libraries

• libstdc++.a — the library implementation in static archive form. If you didn't configure libstdc++ to use shared libraries, this one will always be used. Otherwise it only gets used if the user asks for 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. By default this gets used in preference to the static archive form. N will be a number equal to or greater than 3. But 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.
