KW		 19F<xsubpp> compiles XS code into C. See L<perlutil/xsubpp>.
20
954c1994
GS		 21=for apidoc Amn|char*|CLASS
22Variable which is setup by C<xsubpp> to indicate the
fbe13c60
KW		 23class name for a C++ XS constructor. This is always a C<char*>. See
24C<L</THIS>>.
954c1994
GS		 25
26=for apidoc Amn|(whatever)|RETVAL
27Variable which is setup by C<xsubpp> to hold the return value for an
72d33970 28XSUB. This is always the proper type for the XSUB. See
954c1994
GS		 29L<perlxs/"The RETVAL Variable">.
30
31=for apidoc Amn|(whatever)|THIS
32Variable which is setup by C<xsubpp> to designate the object in a C++
fbe13c60 33XSUB. This is always the proper type for the C++ object. See C<L</CLASS>> and
954c1994
GS		 34L<perlxs/"Using XS With C++">.
35
9f2ea798
DM		 36=for apidoc Amn|I32|ax
37Variable which is setup by C<xsubpp> to indicate the stack base offset,
38used by the C<ST>, C<XSprePUSH> and C<XSRETURN> macros. The C<dMARK> macro
39must be called prior to setup the C<MARK> variable.
40
954c1994
GS		 41=for apidoc Amn|I32|items
42Variable which is setup by C<xsubpp> to indicate the number of
43items on the stack. See L<perlxs/"Variable-length Parameter Lists">.
44
45=for apidoc Amn|I32|ix
46Variable which is setup by C<xsubpp> to indicate which of an
47XSUB's aliases was used to invoke it. See L<perlxs/"The ALIAS: Keyword">.
48
49=for apidoc Am|SV*|ST|int ix
50Used to access elements on the XSUB's stack.
51
eeac5808 52=for apidoc AmU||XS
954c1994 53Macro to declare an XSUB and its C parameter list. This is handled by
56e94d98
KW		 54C<xsubpp>. It is the same as using the more explicit C<XS_EXTERNAL> macro; the
55latter is preferred.
954c1994 56
e64345f8
SM		 57=for apidoc AmU||XS_INTERNAL
58Macro to declare an XSUB and its C parameter list without exporting the symbols.
59This is handled by C<xsubpp> and generally preferable over exporting the XSUB
0cb93b3a 60symbols unnecessarily.
e64345f8 61
eeac5808 62=for apidoc AmU||XS_EXTERNAL
e64345f8 63Macro to declare an XSUB and its C parameter list explicitly exporting the symbols.
e64345f8 64
dbb22d67
KW		 65=for apidoc AmU||XSPROTO
66Macro used by C<L</XS_INTERNAL>> and C<L</XS_EXTERNAL>> to declare a function
67prototype. You probably shouldn't be using this directly yourself.
68
4e5171e9 69=for apidoc Amns||dAX
9f2ea798
DM		 70Sets up the C<ax> variable.
71This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
72
4e5171e9 73=for apidoc Amns||dAXMARK
557b887a
SS		 74Sets up the C<ax> variable and stack marker variable C<mark>.
75This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
76
4e5171e9 77=for apidoc Amns||dITEMS
9f2ea798
DM		 78Sets up the C<items> variable.
79This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
80
4e5171e9 81=for apidoc Amns||dXSARGS
796b6530 82Sets up stack and mark pointers for an XSUB, calling C<dSP> and C<dMARK>.
9f2ea798
DM		 83Sets up the C<ax> and C<items> variables by calling C<dAX> and C<dITEMS>.
84This is usually handled automatically by C<xsubpp>.
954c1994 85
4e5171e9 86=for apidoc Amns||dXSI32
954c1994
GS		 87Sets up the C<ix> variable for an XSUB which has aliases. This is usually
88handled automatically by C<xsubpp>.
89
4e5171e9 90=for apidoc Amns||dUNDERBAR
72d33970
FC		 91Sets up any variable needed by the C<UNDERBAR> macro. It used to define
92C<padoff_du>, but it is currently a noop. However, it is strongly advised
483ce06a 93to still use it for ensuring past and future compatibility.
88037a85 94
78342678 95=for apidoc AmnU||UNDERBAR
796b6530
KW		 96The SV* corresponding to the C<$_> variable. Works even if there
97is a lexical C<$_> in scope.
