=for apidoc Amn|char*|CLASS
|
|
Variable which is setup by C<xsubpp> to indicate the

class name for a C++ XS constructor. This is always a C<char*>. See C<THIS>.
|

|
=for apidoc Amn|(whatever)|RETVAL
|
|
Variable which is setup by C<xsubpp> to hold the return value for an
|
|
XSUB. This is always the proper type for the XSUB. See

|
L<perlxs/"The RETVAL Variable">.
|
|
|
|
=for apidoc Amn|(whatever)|THIS
|
|
Variable which is setup by C<xsubpp> to designate the object in a C++
|
|
XSUB. This is always the proper type for the C++ object. See C<CLASS> and
|
|
L<perlxs/"Using XS With C++">.

|
|
Sets up stack and mark pointers for an XSUB, calling dSP and dMARK. This

|
|
variable to indicate the number of items on the stack.
