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>.
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">.

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++">.

30 Used to access elements on the XSUB's stack.
33 Macro to declare an XSUB and its C parameter list. This is handled by
36 =for apidoc Ams||dXSARGS
37 Sets up stack and mark pointers for an XSUB, calling dSP and dMARK. This

39 variable to indicate the number of items on the stack.
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>.
