| |
| |
| <para> |
| 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> |
| <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. :-) |
| </para> |
| <para><emphasis>[18.4.2.1]/5</emphasis> (bad_alloc), |
| <emphasis>[18.5.2]/5</emphasis> (bad_cast), |
| <emphasis>[18.5.3]/5</emphasis> (bad_typeid), |
| <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. |
| </para> |
| <para><emphasis>[21.1.3.1]/3,4</emphasis>, |
| <emphasis>[21.1.3.2]/2</emphasis>, |
| <emphasis>[21.3]/6 basic_string::iterator, basic_string::const_iterator</emphasis>, |
| <emphasis>[23.*]'s foo::iterator</emphasis>, |
| <emphasis>[27.*]'s foo::*_type</emphasis>, |
| <emphasis>others...</emphasis> |
| 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> |
| <para><emphasis>[21.1.3.1]/5</emphasis> I don't really know about |
| the <type>mbstate_t</type> stuff... see |
| the <link linkend="std.localization.facet.codecvt"><code>codecvt</code> |
| notes</link> for what does exist. |
| </para> |
| <para><emphasis>[22.*]</emphasis> Anything and everything we have on locale |
| implementation will be described under |
| <link linkend="std.localization.locales.locale">Localization</link>. |
| </para> |
| <para><emphasis>[23.*]</emphasis> All of the containers in this clause |
| define <type>size_type</type> as <type>std::size_t</type> and |
| <type>difference_type</type> as <type>std::ptrdiff_t</type>. |
| </para> |
| <para><emphasis>[26.2.8]/9</emphasis> I have no idea what |
| <code>complex<T></code>'s <code>pow(0,0)</code> returns. |
| </para> |
| <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! |
| </para> |
| <para><emphasis>[27.6.1.1.2]</emphasis>, |
| <emphasis>[27.6.2.3]</emphasis> The I/O sentry ctor and dtor can perform |
| additional work than the minimum required. We are not currently taking |
| advantage of this yet. |
| </para> |
| <para><emphasis>[27.7.1.3]/16</emphasis>, |
| <emphasis>[27.8.1.4]/10</emphasis> |
| The effects of <code>pubsetbuf/setbuf</code> are described in the |
| <link linkend="std.io">Input and Output</link> chapter. |
| </para> |
| <para><emphasis>[27.8.1.4]/16</emphasis> Calling <code>fstream::sync</code> when |
| a get area exists will... whatever <code>fflush()</code> does, I think. |
