The ISO standard defines the following phrase:
</p><div class="blockquote"><blockquote class="blockquote"><div class="variablelist"><dl class="variablelist"><dt><span class="term">
<code class="code">[1.3.5] implementation-defined behavior</code>
</span></dt><dd><p>
Behavior, for a well-formed program construct and correct data, that
depends on the implementation <span class="emphasis"><em>and that each implementation
shall document</em></span>.
</p></dd></dl></div></blockquote></div><p>
We do so here, for the C++ library only. Behavior of the
compiler, linker, runtime loader, and other elements of "the
implementation" are documented elsewhere. Everything listed
in Annex B, Implementation Qualities, are also part of the
compiler, not the library.
</p><p>
For each entry, we give the section number of the standard, when
applicable. This list is probably incomplet and inkorrekt.
</p><p>
<span class="emphasis"><em>[1.9]/11 #3</em></span> If <code class="code">isatty(3)</code> is true, then
interactive stream support is implied.
</p><p>
<span class="emphasis"><em>[17.4.4.5]</em></span> Non-reentrant functions are probably best
discussed in the various sections on multithreading (see above).
</p><p><span class="emphasis"><em>[18.1]/4</em></span> The type of <code class="code">NULL</code> is described
under <a class="link" href="support.html#std.support.types.null" title="NULL">Support</a>.
</p><p><span class="emphasis"><em>[18.3]/8</em></span> Even though it's listed in the library
sections, libstdc++ has zero control over what the cleanup code hands
back to the runtime loader. Talk to the compiler people. :-)
</p><p><span class="emphasis"><em>[18.4.2.1]/5</em></span> (bad_alloc),
<span class="emphasis"><em>[18.5.2]/5</em></span> (bad_cast),
<span class="emphasis"><em>[18.5.3]/5</em></span> (bad_typeid),
<span class="emphasis"><em>[18.6.1]/8</em></span> (exception),
<span class="emphasis"><em>[18.6.2.1]/5</em></span> (bad_exception): The <code class="code">what()</code>
member function of class <code class="code">std::exception</code>, and these other
classes publicly derived from it, simply returns the name of the
class. But they are the <span class="emphasis"><em>mangled</em></span> names; you will need to call
<code class="code">c++filt</code> and pass the names as command-line parameters to
demangle them, or call a
<a class="link" href="ext_demangling.html" title="Chapter 29. Demangling">runtime demangler function</a>.
(The classes in <code class="code">&lt;stdexcept&gt;</code> have constructors which
require an argument to use later for <code class="code">what()</code> calls, so the
problem of <code class="code">what()</code>'s value does not arise in most
user-defined exceptions.)
</p><p><span class="emphasis"><em>[18.5.1]/7</em></span> The return value of
<code class="code">std::type_info::name()</code> is the mangled type name (see the
previous entry for more).
</p><p><span class="emphasis"><em>[20.1.5]/5</em></span> <span class="emphasis"><em>"Implementors are encouraged to
supply libraries that can accept allocators that encapsulate more
general memory models and that support non-equal instances. In such
implementations, any requirements imposed on allocators by containers
beyond those requirements that appear in Table 32, and the semantics
of containers and algorithms when allocator instances compare
non-equal, are implementation-defined."</em></span> There is experimental
support for non-equal allocators in the standard containers in C++98
mode. There are no additional requirements on allocators. It is undefined
behaviour to swap two containers if their allocators are not equal.
</p><p><span class="emphasis"><em>[21.1.3.1]/3,4</em></span>,

<span class="emphasis"><em>others...</em></span>
Nope, these types are called implementation-defined because you
shouldn't be taking advantage of their underlying types. Listing them
here would defeat the purpose. :-)
</p><p><span class="emphasis"><em>[21.1.3.1]/5</em></span> I don't really know about
the <span class="type">mbstate_t</span> stuff... see
the <a class="link" href="facets.html#std.localization.facet.codecvt" title="codecvt"><code class="code">codecvt</code>
notes</a> for what does exist.
</p><p><span class="emphasis"><em>[22.*]</em></span> Anything and everything we have on locale
implementation will be described under
<a class="link" href="localization.html#std.localization.locales.locale" title="locale">Localization</a>.
</p><p><span class="emphasis"><em>[26.2.8]/9</em></span> I have no idea what
<code class="code">complex&lt;T&gt;</code>'s <code class="code">pow(0,0)</code> returns.
</p><p><span class="emphasis"><em>[27.4.2.4]/2</em></span> Calling
<code class="code">std::ios_base::sync_with_stdio</code> after I/O has already been
performed on the standard stream objects will
flush the buffers, and
destroy and recreate the underlying buffer instances. Whether or not
the previously-written I/O is destroyed in this process depends mostly
on the <code class="code">--enable-libio</code> choice: for stdio, if the written
data is already in the stdio buffer, the data may be completely safe!
</p><p><span class="emphasis"><em>[27.6.1.1.2]</em></span>,
<span class="emphasis"><em>[27.6.2.3]</em></span> The I/O sentry ctor and dtor can perform
additional work than the minimum required. We are not currently taking
advantage of this yet.
</p><p><span class="emphasis"><em>[27.7.1.3]/16</em></span>,
<span class="emphasis"><em>[27.8.1.4]/10</em></span>
The effects of <code class="code">pubsetbuf/setbuf</code> are described in the
<a class="link" href="io.html" title="Chapter 13.  Input and Output">Input and Output</a> chapter.
</p><p><span class="emphasis"><em>[27.8.1.4]/16</em></span> Calling <code class="code">fstream::sync</code> when
a get area exists will... whatever <code class="code">fflush()</code> does, I think.
