17=for apidoc_section $XS
18
19F<xsubpp> compiles XS code into C. See L<perlutil/xsubpp>.
20
21=for comment
22Some variables below are flagged with 'u' because Devel::PPPort can't currently
23readily test them as they spring into existence by compiling with xsubpp.
24
25=for apidoc Amnu|char*|CLASS
26Variable which is setup by C<xsubpp> to indicate the
27class name for a C++ XS constructor. This is always a C<char*>. See
28C<L</THIS>>.
29
30=for apidoc Amnu|type|RETVAL
31Variable which is setup by C<xsubpp> to hold the return value for an
32XSUB. This is always the proper type for the XSUB. See
33L<perlxs/"The RETVAL Variable">.
34
35=for apidoc Amnu|type|THIS
36Variable which is setup by C<xsubpp> to designate the object in a C++
37XSUB. This is always the proper type for the C++ object. See C<L</CLASS>> and
38L<perlxs/"Using XS With C++">.
39
40=for apidoc Amn|I32|ax
41Variable which is setup by C<xsubpp> to indicate the stack base offset,
42used by the C<ST>, C<XSprePUSH> and C<XSRETURN> macros. The C<dMARK> macro
43must be called prior to setup the C<MARK> variable.
44
45=for apidoc Amn|I32|items
46Variable which is setup by C<xsubpp> to indicate the number of
47items on the stack. See L<perlxs/"Variable-length Parameter Lists">.
48
49=for apidoc Amn|I32|ix
50Variable which is setup by C<xsubpp> to indicate which of an
51XSUB's aliases was used to invoke it. See L<perlxs/"The ALIAS: Keyword">.
52
53=for apidoc Am|SV*|ST|int ix
54Used to access elements on the XSUB's stack.
55
56=for apidoc Ay||XS|name
57Macro to declare an XSUB and its C parameter list. This is handled by
58C<xsubpp>. It is the same as using the more explicit C<XS_EXTERNAL> macro; the
59latter is preferred.
60
61=for apidoc Ayu||XS_INTERNAL|name
62Macro to declare an XSUB and its C parameter list without exporting the symbols.
63This is handled by C<xsubpp> and generally preferable over exporting the XSUB
64symbols unnecessarily.
65
66=for comment
67XS_INTERNAL marked 'u' because declaring a function static within our test
68function doesn't work
69
70=for apidoc Ay||XS_EXTERNAL|name
71Macro to declare an XSUB and its C parameter list explicitly exporting the symbols.
72
73=for apidoc Ay||XSPROTO|name
74Macro used by C<L</XS_INTERNAL>> and C<L</XS_EXTERNAL>> to declare a function
75prototype. You probably shouldn't be using this directly yourself.
76
77=for apidoc Amns||dAX
78Sets up the C<ax> variable.
79This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
80
81=for apidoc Amns||dAXMARK
82Sets up the C<ax> variable and stack marker variable C<mark>.
83This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
84
85=for apidoc Amns||dITEMS
86Sets up the C<items> variable.
87This is usually handled automatically by C<xsubpp> by calling C<dXSARGS>.
88
89=for apidoc Amns||dXSARGS
90Sets up stack and mark pointers for an XSUB, calling C<dSP> and C<dMARK>.
91Sets up the C<ax> and C<items> variables by calling C<dAX> and C<dITEMS>.
92This is usually handled automatically by C<xsubpp>.
93
94=for apidoc Amns||dXSI32
95Sets up the C<ix> variable for an XSUB which has aliases. This is usually
96handled automatically by C<xsubpp>.
97
98=for apidoc Amns||dUNDERBAR
99Sets up any variable needed by the C<UNDERBAR> macro. It used to define
100C<padoff_du>, but it is currently a noop. However, it is strongly advised
101to still use it for ensuring past and future compatibility.
102
103=for apidoc AmnU||UNDERBAR
104The SV* corresponding to the C<$_> variable. Works even if there
105is a lexical C<$_> in scope.
