1.11 Writing Extensions in C++

</H1>

<P>
It is possible to write extension modules in C++.  Some restrictions
apply.  If the main program (the Python interpreter) is compiled and
linked by the C compiler, global or static objects with constructors
cannot be used.  This is not a problem if the main program is linked
by the C++ compiler.  Functions that will be called by the
Python interpreter (in particular, module initialization functions)
have to be declared using <code>extern "C"</code>.
It is unnecessary to enclose the Python header files in
<code>extern "C" {...}</code> -- they use this form already if the symbol
"<tt class="samp">__cplusplus</tt>" is defined (all recent C++ compilers define this
symbol).

<P>
