=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>.

=for apidoc Ams||dUNDERBAR
Sets up the C<padoff_du> variable for an XSUB that wishes to use
C<UNDERBAR>.

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

=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.

=for apidoc Am|void|XST_mNV|int pos|NV nv
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_UV|IV uv
Return an integer from an XSUB immediately.  Uses C<XST_mUV>.

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

Return a copy of a string from an XSUB immediately.  Uses C<XST_mPV>.

=for apidoc Ams||XSRETURN_NO
Return C<&PL_sv_no> from an XSUB immediately.  Uses C<XST_mNO>.

=for apidoc Ams||XSRETURN_YES
Return C<&PL_sv_yes> from an XSUB immediately.  Uses C<XST_mYES>.

=for apidoc Ams||XSRETURN_UNDEF
Return C<&PL_sv_undef> from an XSUB immediately.  Uses C<XST_mUNDEF>.

=for apidoc Ams||XSRETURN_EMPTY

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

=for apidoc AmU||newXSproto|char* name|XSUBADDR_t f|char* filename|const char *proto
Used by C<xsubpp> to hook up XSUBs as Perl subs.  Adds Perl prototypes to
the subs.

=for apidoc AmU||XS_VERSION
The version identifier for an XS module.  This is usually
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">.

954c1994 GS	19	=for apidoc Amn\|char*\|CLASS
	20	Variable which is setup by C<xsubpp> to indicate the
	21	class name for a C++ XS constructor. This is always a C<char*>. See C<THIS>.
	22
	23	=for apidoc Amn\|(whatever)\|RETVAL
	24	Variable which is setup by C<xsubpp> to hold the return value for an
	25	XSUB. This is always the proper type for the XSUB. See
	26	L<perlxs/"The RETVAL Variable">.
	27
	28	=for apidoc Amn\|(whatever)\|THIS
	29	Variable which is setup by C<xsubpp> to designate the object in a C++
	30	XSUB. This is always the proper type for the C++ object. See C<CLASS> and
	31	L<perlxs/"Using XS With C++">.
	32
9f2ea798 DM	33	=for apidoc Amn\|I32\|ax
	34	Variable which is setup by C<xsubpp> to indicate the stack base offset,
	35	used by the C<ST>, C<XSprePUSH> and C<XSRETURN> macros. The C<dMARK> macro
	36	must be called prior to setup the C<MARK> variable.
	37
954c1994 GS	38	=for apidoc Amn\|I32\|items
	39	Variable which is setup by C<xsubpp> to indicate the number of
	40	items on the stack. See L<perlxs/"Variable-length Parameter Lists">.
	41
	42	=for apidoc Amn\|I32\|ix
	43	Variable which is setup by C<xsubpp> to indicate which of an
	44	XSUB's aliases was used to invoke it. See L<perlxs/"The ALIAS: Keyword">.
	45

	47	Used to access elements on the XSUB's stack.
	48
	49	=for apidoc AmU\|\|XS
	50	Macro to declare an XSUB and its C parameter list. This is handled by
	51	C<xsubpp>.
	52
9f2ea798 DM	53	=for apidoc Ams\|\|dAX
	54	Sets up the C<ax> variable.
	55	This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
	56
	57	=for apidoc Ams\|\|dITEMS
	58	Sets up the C<items> variable.
	59	This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
	60
954c1994	61	=for apidoc Ams\|\|dXSARGS
9f2ea798 DM	62	Sets up stack and mark pointers for an XSUB, calling dSP and dMARK.
	63	Sets up the C<ax> and C<items> variables by calling C<dAX> and C<dITEMS>.
	64	This is usually handled automatically by C<xsubpp>.
954c1994 GS	65
	66	=for apidoc Ams\|\|dXSI32
	67	Sets up the C<ix> variable for an XSUB which has aliases. This is usually
	68	handled automatically by C<xsubpp>.
	69
88037a85 RGS	70	=for apidoc Ams\|\|dUNDERBAR
	71	Sets up the C<padoff_du> variable for an XSUB that wishes to use
	72	C<UNDERBAR>.
	73
	74	=for apidoc AmU\|\|UNDERBAR
	75	The SV* corresponding to the $_ variable. Works even if there
	76	is a lexical $_ in scope.
