The ISO standard defines the following phrase:
|
|
</para>
|
|
<blockquote>
|
|
<variablelist>
|
|
<varlistentry>
|
|
<term>
|
|
<code>[1.3.5] implementation-defined behavior</code>
|
|
</term>
|

<listitem>
|

<para>
|
|
Behavior, for a well-formed program construct and correct data, that
|
|
depends on the implementation <emphasis>and that each implementation
|
|
shall document</emphasis>.
|
|
</para>
|
|
</listitem>
|
|
</varlistentry>
|
|
</variablelist>
|
|
</blockquote>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
For each entry, we give the section number of the standard, when
|
|
applicable. This list is probably incomplet and inkorrekt.
|
|
</para>
|
|
<para>
|
|
<emphasis>[1.9]/11 #3</emphasis> If <code>isatty(3)</code> is true, then

interactive stream support is implied.

<para>
|
|
<emphasis>[17.4.4.5]</emphasis> Non-reentrant functions are probably best
|
|
discussed in the various sections on multithreading (see above).
|
|
</para>
|
|
<!-- [17.4.4.8]/3 says any function that doesn't have an exception-spec
|
|
can throw whatever we want; see also its footnote. Let's list those
|
|
in the sections where the function itself occurs.
|
|
-->
|

<para><emphasis>[18.1]/4</emphasis> The type of <code>NULL</code> is described
|

under <link linkend="std.support.types.null">Support</link>.
|
|
</para>
|
|
<para><emphasis>[18.3]/8</emphasis> 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. :-)

<emphasis>[18.6.1]/8</emphasis> (exception),

<emphasis>[18.6.2.1]/5</emphasis> (bad_exception): The <code>what()</code>
|
|
member function of class <code>std::exception</code>, and these other
|
|
classes publicly derived from it, returns the name of the
|
|
class, e.g. <literal>"std::bad_alloc"</literal>.
|
|
</para>
|
|
<para><emphasis>[18.5.1]/7</emphasis> The return value of
|
|
<code>std::type_info::name()</code> is the mangled type name.
|
|
You will need to call <code>c++filt</code> and pass the names as
|
|
command-line parameters to demangle them, or call a
|
|
<link linkend="manual.ext.demangle">runtime demangler function</link>.
|
|
</para>
|
|
<para><emphasis>[20.1.5]/5</emphasis> <emphasis>"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."</emphasis> 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.

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. :-)

<para><emphasis>[27.4.2.4]/2</emphasis> Calling
|
|
<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 <!-- this line might go away -->
|
|
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>--enable-libio</code> choice: for stdio, if the written
|
|
data is already in the stdio buffer, the data may be completely safe!
