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>.
XSUB. This is always the proper type for the C++ object. See C<CLASS> and
L<perlxs/"Using XS With C++">.

+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.

Variable which is setup by C<xsubpp> to indicate the number of
items on the stack. See L<perlxs/"Variable-length Parameter Lists">.
Macro to declare an XSUB and its C parameter list. This is handled by
C<xsubpp>.

=for apidoc Am|void|XST_mIV|int pos|IV iv
Place an integer into the specified position C<pos> on the stack. The
value is stored in a new mortal SV.
Return an integer from an XSUB immediately. Uses C<XST_mIV>.
