ccfc67b7 18
954c1994
GS		 19=for apidoc Amn|char*|CLASS
20Variable which is setup by C<xsubpp> to indicate the
21class name for a C++ XS constructor. This is always a C<char*>. See C<THIS>.
22
23=for apidoc Amn|(whatever)|RETVAL
24Variable which is setup by C<xsubpp> to hold the return value for an
72d33970 25XSUB. This is always the proper type for the XSUB. See
954c1994
GS		 26L<perlxs/"The RETVAL Variable">.
27
28=for apidoc Amn|(whatever)|THIS
29Variable which is setup by C<xsubpp> to designate the object in a C++
30XSUB. This is always the proper type for the C++ object. See C<CLASS> and
31L<perlxs/"Using XS With C++">.
32
9f2ea798
DM		 33=for apidoc Amn|I32|ax
34Variable which is setup by C<xsubpp> to indicate the stack base offset,
35used by the C<ST>, C<XSprePUSH> and C<XSRETURN> macros. The C<dMARK> macro
36must be called prior to setup the C<MARK> variable.
37
954c1994
GS		 38=for apidoc Amn|I32|items
39Variable which is setup by C<xsubpp> to indicate the number of
40items on the stack. See L<perlxs/"Variable-length Parameter Lists">.
41
42=for apidoc Amn|I32|ix
43Variable which is setup by C<xsubpp> to indicate which of an
44XSUB's aliases was used to invoke it. See L<perlxs/"The ALIAS: Keyword">.
45
46=for apidoc Am|SV*|ST|int ix
47Used to access elements on the XSUB's stack.
48
49=for apidoc AmU||XS
50Macro to declare an XSUB and its C parameter list. This is handled by
72d33970 51C<xsubpp>. It is the same as using the more explicit XS_EXTERNAL macro.
954c1994 52
e64345f8
S		 53=for apidoc AmU||XS_INTERNAL
54Macro to declare an XSUB and its C parameter list without exporting the symbols.
55This is handled by C<xsubpp> and generally preferable over exporting the XSUB
0cb93b3a 56symbols unnecessarily.
e64345f8
S		 57
58=for apidoc AmU||XS_EXTERNAL
59Macro to declare an XSUB and its C parameter list explicitly exporting the symbols.
e64345f8 60
9f2ea798
DM		 61=for apidoc Ams||dAX
62Sets up the C<ax> variable.
63This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
64
557b887a
SS		 65=for apidoc Ams||dAXMARK
66Sets up the C<ax> variable and stack marker variable C<mark>.
67This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
68
9f2ea798
DM		 69=for apidoc Ams||dITEMS
70Sets up the C<items> variable.
71This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
72
954c1994 73=for apidoc Ams||dXSARGS
9f2ea798
DM		 74Sets up stack and mark pointers for an XSUB, calling dSP and dMARK.
75Sets up the C<ax> and C<items> variables by calling C<dAX> and C<dITEMS>.
76This is usually handled automatically by C<xsubpp>.
954c1994
GS		 77
78=for apidoc Ams||dXSI32
79Sets up the C<ix> variable for an XSUB which has aliases. This is usually
80handled automatically by C<xsubpp>.
81
88037a85 82=for apidoc Ams||dUNDERBAR
72d33970
FC		 83Sets up any variable needed by the C<UNDERBAR> macro. It used to define
84C<padoff_du>, but it is currently a noop. However, it is strongly advised
483ce06a 85to still use it for ensuring past and future compatibility.
88037a85
RGS		 86
87=for apidoc AmU||UNDERBAR
72d33970 88The SV* corresponding to the $_ variable. Works even if there
88037a85
RGS		 89is a lexical $_ in scope.
