7 | =for apidoc Amn|char*|CLASS |
8 | Variable which is setup by C<xsubpp> to indicate the |
9 | class name for a C++ XS constructor. This is always a C<char*>. See C<THIS>. |
10 | |
11 | =for apidoc Amn|(whatever)|RETVAL |
12 | Variable which is setup by C<xsubpp> to hold the return value for an |
13 | XSUB. This is always the proper type for the XSUB. See |
14 | L<perlxs/"The RETVAL Variable">. |
15 | |
16 | =for apidoc Amn|(whatever)|THIS |
17 | Variable which is setup by C<xsubpp> to designate the object in a C++ |
18 | XSUB. This is always the proper type for the C++ object. See C<CLASS> and |
19 | L<perlxs/"Using XS With C++">. |

21 | =for apidoc Amn|I32|items |
22 | Variable which is setup by C<xsubpp> to indicate the number of |
23 | items on the stack. See L<perlxs/"Variable-length Parameter Lists">. |
24 | |
25 | =for apidoc Amn|I32|ix |
26 | Variable which is setup by C<xsubpp> to indicate which of an |
27 | XSUB's aliases was used to invoke it. See L<perlxs/"The ALIAS: Keyword">. |
28 | |
29 | =for apidoc Am|SV*|ST|int ix |
30 | Used to access elements on the XSUB's stack. |
31 | |
32 | =for apidoc AmU||XS |
33 | Macro to declare an XSUB and its C parameter list. This is handled by |
34 | C<xsubpp>. |
35 | |
36 | =for apidoc Ams||dXSARGS |
37 | Sets up stack and mark pointers for an XSUB, calling dSP and dMARK. This |
38 | is usually handled automatically by C<xsubpp>. Declares the C<items> |
39 | variable to indicate the number of items on the stack. |
40 | |
41 | =for apidoc Ams||dXSI32 |
42 | Sets up the C<ix> variable for an XSUB which has aliases. This is usually |
43 | handled automatically by C<xsubpp>. |
