=head1 Variables created by C<xsubpp> and C<xsubpp> internal functions

=for apidoc Amn|char*|CLASS
Variable which is setup by C<xsubpp> to indicate the 
class name for a C++ XS constructor.  This is always a C<char*>.  See C<THIS>.

=for apidoc Amn|(whatever)|RETVAL
Variable which is setup by C<xsubpp> to hold the return value for an 
XSUB. This is always the proper type for the XSUB. See 
L<perlxs/"The RETVAL Variable">.

=for apidoc Amn|(whatever)|THIS
Variable which is setup by C<xsubpp> to designate the object in a C++ 
XSUB.  This is always the proper type for the C++ object.  See C<CLASS> and 
L<perlxs/"Using XS With C++">.

=for apidoc Amn|I32|ax
Variable which is setup by C<xsubpp> to indicate the stack base offset,
used by the C<ST>, C<XSprePUSH> and C<XSRETURN> macros.  The C<dMARK> macro
must be called prior to setup the C<MARK> variable.

=for apidoc Amn|I32|items
Variable which is setup by C<xsubpp> to indicate the number of 
items on the stack.  See L<perlxs/"Variable-length Parameter Lists">.

=for apidoc Amn|I32|ix
Variable which is setup by C<xsubpp> to indicate which of an 
XSUB's aliases was used to invoke it.  See L<perlxs/"The ALIAS: Keyword">.

=for apidoc Am|SV*|ST|int ix
Used to access elements on the XSUB's stack.

=for apidoc AmU||XS
Macro to declare an XSUB and its C parameter list.  This is handled by
C<xsubpp>. It is the same as using the more explicit XS_EXTERNAL macro.

=for apidoc AmU||XS_INTERNAL
Macro to declare an XSUB and its C parameter list without exporting the symbols.
This is handled by C<xsubpp> and generally preferable over exporting the XSUB
symbols unnecessarily.

=for apidoc AmU||XS_EXTERNAL
Macro to declare an XSUB and its C parameter list explicitly exporting the symbols.

=for apidoc Ams||dAX
Sets up the C<ax> variable.
This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.

=for apidoc Ams||dAXMARK
Sets up the C<ax> variable and stack marker variable C<mark>.
This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.

=for apidoc Ams||dITEMS
Sets up the C<items> variable.
This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.

=for apidoc Ams||dXSARGS
Sets up stack and mark pointers for an XSUB, calling dSP and dMARK.
Sets up the C<ax> and C<items> variables by calling C<dAX> and C<dITEMS>.
This is usually handled automatically by C<xsubpp>.

=for apidoc Ams||dXSI32
Sets up the C<ix> variable for an XSUB which has aliases.  This is usually
handled automatically by C<xsubpp>.

=for apidoc Ams||dUNDERBAR
Sets up any variable needed by the C<UNDERBAR> macro. It used to define
C<padoff_du>, but it is currently a noop. However, it is strongly advised
to still use it for ensuring past and future compatibility.

=for apidoc AmU||UNDERBAR
The SV* corresponding to the $_ variable. Works even if there
is a lexical $_ in scope.
