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
25XSUB. This is always the proper type for the XSUB. See
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
51C<xsubpp>.
52
9f2ea798
DM
53=for apidoc Ams||dAX
54Sets up the C<ax> variable.
55This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
56
57=for apidoc Ams||dITEMS
58Sets up the C<items> variable.
59This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
60
954c1994 61=for apidoc Ams||dXSARGS
9f2ea798
DM
62Sets up stack and mark pointers for an XSUB, calling dSP and dMARK.
63Sets up the C<ax> and C<items> variables by calling C<dAX> and C<dITEMS>.
64This is usually handled automatically by C<xsubpp>.
954c1994
GS
65
66=for apidoc Ams||dXSI32
67Sets up the C<ix> variable for an XSUB which has aliases. This is usually
68handled automatically by C<xsubpp>.
69
88037a85
RGS
70=for apidoc Ams||dUNDERBAR
71Sets up the C<padoff_du> variable for an XSUB that wishes to use
72C<UNDERBAR>.
73
74=for apidoc AmU||UNDERBAR
75The SV* corresponding to the $_ variable. Works even if there
76is a lexical $_ in scope.
