1058      We do so here, for the C++ library only.  Behavior of the
1059      compiler, linker, runtime loader, and other elements of &quot;the
1060      implementation&quot; are documented elsewhere.  Everything listed
1061      in Annex B, Implementation Qualities, are also part of the
1062      compiler, not the library.
1063    </para>
1064    <para>
1065      For each entry, we give the section number of the standard, when
1066      applicable.  This list is probably incomplet and inkorrekt.

1073      <emphasis>[17.4.4.5]</emphasis> Non-reentrant functions are probably best

1076    <!-- [17.4.4.8]/3 says any function that doesn't have an exception-spec
1077         can throw whatever we want; see also its footnote.  Let's list those
1078         in the sections where the function itself occurs.

1080    <para><emphasis>[18.1]/4</emphasis> The type of <code>NULL</code> is described

1083    <para><emphasis>[18.3]/8</emphasis> Even though it's listed in the library
1084       sections, libstdc++ has zero control over what the cleanup code hands

1092       member function of class <code>std::exception</code>, and these other
1093       classes publicly derived from it, simply returns the name of the
1094       class.  But they are the <emphasis>mangled</emphasis> names; you will need to call
1095       <code>c++filt</code> and pass the names as command-line parameters to
1096       demangle them, or call a
1097       <ulink url="../18_support/howto.html#5">runtime demangler function</ulink>.
1098       (The classes in <code>&lt;stdexcept&gt;</code> have constructors which
1099       require an argument to use later for <code>what()</code> calls, so the
1100       problem of <code>what()</code>'s value does not arise in most
1101       user-defined exceptions.)

1103    <para><emphasis>[18.5.1]/7</emphasis> The return value of

1110       implementations, any requirements imposed on allocators by containers
1111       beyond those requirements that appear in Table 32, and the semantics

1114       have any allocators which compare non-equal, so we can't describe how
1115       they behave.

1122       Nope, these types are called implementation-defined because you
1123       shouldn't be taking advantage of their underlying types.  Listing them

1141       destroy and recreate the underlying buffer instances.  Whether or not
1142       the previously-written I/O is destroyed in this process depends mostly
1143       on the --enable-libio choice:  for stdio, if the written data is
1144       already in the stdio buffer, the data may be completely safe!
