<H2><A NAME="2">Automatically-generated operators</A></H2> <H2><A NAME="2"><TT>auto_ptr</TT> inside container classes</A></H2>
<P>Many programs (for that matter, many of the Standard algorithms <P>All of the <A HREF="../23_containers/howto.html">containers</A>
and containers) require that you write comparison operators for described in the standard library require their contained types
your classes, like <TT>operator&gt;=</TT>. As any mathmatician to have, among other things, a copy contructor like this:
will tell you, once you have defined equality and ordering, all
of the other comparisons are easily defined in terms of those two.
</P>
<P>The Committee agrees. So, once you have written
<TT>operator==</TT> and <TT>operator&lt;</TT> for your class
(whether they are global or member functions is up to you), you
can have the compiler do the grunt-work of generating the rest:
<PRE> <PRE>
#include &lt;header_with_my_op==_and_op&lt;_defined&gt; struct My_Type
#include &lt;utility&gt; {
using std::rel_ops; // note the nested namespace! My_Type (My_Type const&amp;);
};
... </PRE>
if ((obj1 != obj2) || (obj3 >= obj4)) foo(); Note the const keyword; the object being copied shouldn't change.
The template class <TT>auto_ptr</TT> (called AP here) does not
meet this requirement. Creating a new AP by copying an existing
one transfers ownership of the pointed-to object, which means that
the AP being copied must change, which in turn means that the
copy ctors of AP do not take const objects.
</P>
<P>The resulting rule is simple: <EM>Never ever use a container of
auto_ptr objects.</EM> The standard says that undefined behavior
is the result, but it is guaranteed to be messy.
</P>
<P>To prevent you from doing this to yourself, the
<A HREF="../19_diagnostics/howto.html#3">concept checks</A> built
in to this implementation will issue an error if you try to
compile code like this:
<PRE>
#include &lt;vector&gt;
#include &lt;memory&gt;
void f()
{
std::vector&lt; std::auto_ptr&lt;int&gt; &gt; vec_ap_int;
}
</PRE>
Should you try this, you will see an error along the lines of the
following (look through the ugly line-wrapping):
<PRE>
/installdir/include/g++-v3/bits/concept_checks.h: In
static member function `static _Type
<B>_STL_ERROR::__const_parameter_required_for_copy_constructor</B>(_Type, const
_Type&amp;) [with _Type = std::auto_ptr&lt;int&gt;]':

[with _Tp1 = int, _Tp = int]' discards qualifiers
</PRE> </PRE>
See the highlighted error? It starts with a message in all caps
to get your attention.

<H2><A NAME="6">Deriving a stream buffer</A></H2>
<P>Creating your own stream buffers for I/O can be remarkably easy.
If you are interested in doing so, we highly recommend two very
excellent books: <EM>Standard C++ IOStreams and Locales</EM> by
Langer and Kreft, ISBN 0-201-18395-1, and
<A HREF="http://www.josuttis.com/libbook/">The C++ Standard Library</A>
by Nicolai Josuttis, ISBN 0-201-37926-0. Both are published by
Addison-Wesley, who isn't paying us a cent for saying that, honest.
</P>
<P>Here is a simple example, io/outbuf1, from the Josuttis text. It
transforms everything sent through it to uppercase. This version
assumes many things about the nature of the character type being
used (for more information, read the books or the newsgroups):
<PRE>
#include &lt;iostream&gt;
#include &lt;streambuf&gt;
#include &lt;locale&gt;
#include &lt;cstdio&gt;
class outbuf : public std::streambuf
{
protected:
/* central output function
* - print characters in uppercase mode
*/
virtual int_type overflow (int_type c) {
if (c != EOF) {
// convert lowercase to uppercase
c = std::toupper(static_cast&lt;char&gt;(c),getloc());
// and write the character to the standard output
if (putchar(c) == EOF) {
return EOF;
}
}
return c;
}
};
int main()
{
// create special output buffer
outbuf ob;
// initialize output stream with that output buffer
std::ostream out(&ob);
out &lt;&lt; "31 hexadecimal: "
&lt;&lt; std::hex &lt;&lt; 31 &lt;&lt; std::endl;
return 0;
}
</PRE>
Try it yourself!
</P>

<H2><A NAME="3_3">3.3 Building DEC OSF kills the assembler</A></H2>
<P>The <TT>atomicity.h</TT> header for the Alpha processor
currently uses pseudo-operators which the DEC assembler
doesn't understand (in particular, .subsection and .previous).
The simple solution is to install GNU <TT>as</TT> and arrange
for the GCC build to use it (or merge the sources and build
it during the bootstrap).

<P>Anyone who
<A HREF="http://gcc.gnu.org/ml/libstdc++/2000-12/msg00279.html">knows
the DEC assembler well enough</A> to provide the equivalent of
these two pseudos would win praise and accolades from many.
