=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>.

=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||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>.

=head1 Stack Manipulation Macros

=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.

Place a double into the specified position C<pos> on the stack.  The value
is stored in a new mortal SV.

=for apidoc Am|void|XST_mPV|int pos|char* str
Place a copy of a string into the specified position C<pos> on the stack. 
The value is stored in a new mortal SV.

=for apidoc Am|void|XST_mNO|int pos
Place C<&PL_sv_no> into the specified position C<pos> on the
stack.

=for apidoc Am|void|XST_mYES|int pos
Place C<&PL_sv_yes> into the specified position C<pos> on the
stack.

=for apidoc Am|void|XST_mUNDEF|int pos
Place C<&PL_sv_undef> into the specified position C<pos> on the
stack.

=for apidoc Am|void|XSRETURN|int nitems
Return from XSUB, indicating number of items on the stack.  This is usually
handled by C<xsubpp>.

=for apidoc Am|void|XSRETURN_IV|IV iv
Return an integer from an XSUB immediately.  Uses C<XST_mIV>.

=for apidoc Am|void|XSRETURN_NV|NV nv
Return a double from an XSUB immediately.  Uses C<XST_mNV>.

=for apidoc Am|void|XSRETURN_PV|char* str

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

=for apidoc AmU||newXSproto
Used by C<xsubpp> to hook up XSUBs as Perl subs.  Adds Perl prototypes to
the subs.

=for apidoc AmU||XS_VERSION

handled automatically by C<ExtUtils::MakeMaker>.  See C<XS_VERSION_BOOTCHECK>.

=for apidoc Ams||XS_VERSION_BOOTCHECK
Macro to verify that a PM module's $VERSION variable matches the XS
module's C<XS_VERSION> variable.  This is usually handled automatically by
C<xsubpp>.  See L<perlxs/"The VERSIONCHECK: Keyword">.

	130	Return from XSUB, indicating number of items on the stack. This is usually
	131	handled by C<xsubpp>.

	158	the subs.
	159
	160	=for apidoc AmU\|\|XS_VERSION
	161	The version identifier for an XS module. This is usually
