954c1994
GS		 19=for apidoc Amn|char*|CLASS
20Variable which is setup by C<xsubpp> to indicate the
fbe13c60
KW		 21class name for a C++ XS constructor. This is always a C<char*>. See
22C<L</THIS>>.
954c1994
GS		 23
24=for apidoc Amn|(whatever)|RETVAL
25Variable which is setup by C<xsubpp> to hold the return value for an
72d33970 26XSUB. This is always the proper type for the XSUB. See
954c1994
GS		 27L<perlxs/"The RETVAL Variable">.
28
29=for apidoc Amn|(whatever)|THIS
30Variable which is setup by C<xsubpp> to designate the object in a C++
fbe13c60 31XSUB. This is always the proper type for the C++ object. See C<L</CLASS>> and
954c1994
GS		 32L<perlxs/"Using XS With C++">.
33
9f2ea798
DM		 34=for apidoc Amn|I32|ax
35Variable which is setup by C<xsubpp> to indicate the stack base offset,
36used by the C<ST>, C<XSprePUSH> and C<XSRETURN> macros. The C<dMARK> macro
37must be called prior to setup the C<MARK> variable.
38
954c1994
GS		 39=for apidoc Amn|I32|items
40Variable which is setup by C<xsubpp> to indicate the number of
41items on the stack. See L<perlxs/"Variable-length Parameter Lists">.
42
43=for apidoc Amn|I32|ix
44Variable which is setup by C<xsubpp> to indicate which of an
45XSUB's aliases was used to invoke it. See L<perlxs/"The ALIAS: Keyword">.
46
47=for apidoc Am|SV*|ST|int ix
48Used to access elements on the XSUB's stack.
49
78342678 50=for apidoc AmnU||XS
954c1994 51Macro to declare an XSUB and its C parameter list. This is handled by
796b6530 52C<xsubpp>. It is the same as using the more explicit C<XS_EXTERNAL> macro.
954c1994 53
e64345f8
S		 54=for apidoc AmU||XS_INTERNAL
55Macro to declare an XSUB and its C parameter list without exporting the symbols.
56This is handled by C<xsubpp> and generally preferable over exporting the XSUB
0cb93b3a 57symbols unnecessarily.
e64345f8 58
78342678 59=for apidoc AmnU||XS_EXTERNAL
e64345f8 60Macro to declare an XSUB and its C parameter list explicitly exporting the symbols.
e64345f8 61
4e5171e9 62=for apidoc Amns||dAX
9f2ea798
DM		 63Sets up the C<ax> variable.
64This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
65
4e5171e9 66=for apidoc Amns||dAXMARK
557b887a
SS		 67Sets up the C<ax> variable and stack marker variable C<mark>.
68This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
69
4e5171e9 70=for apidoc Amns||dITEMS
9f2ea798
DM		 71Sets up the C<items> variable.
72This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
73
4e5171e9 74=for apidoc Amns||dXSARGS
796b6530 75Sets up stack and mark pointers for an XSUB, calling C<dSP> and C<dMARK>.
9f2ea798
DM		 76Sets up the C<ax> and C<items> variables by calling C<dAX> and C<dITEMS>.
77This is usually handled automatically by C<xsubpp>.
954c1994 78
4e5171e9 79=for apidoc Amns||dXSI32
954c1994
GS		 80Sets up the C<ix> variable for an XSUB which has aliases. This is usually
81handled automatically by C<xsubpp>.
82
4e5171e9 83=for apidoc Amns||dUNDERBAR
72d33970
FC		 84Sets up any variable needed by the C<UNDERBAR> macro. It used to define
85C<padoff_du>, but it is currently a noop. However, it is strongly advised
483ce06a 86to still use it for ensuring past and future compatibility.
88037a85 87
78342678 88=for apidoc AmnU||UNDERBAR
796b6530
KW		 89The SV* corresponding to the C<$_> variable. Works even if there
90is a lexical C<$_> in scope.
