=head1 Stack Manipulation Macros

=for apidoc AmU||SP
Stack pointer.  This is usually handled by C<xsubpp>.  See C<dSP> and
C<SPAGAIN>.

=for apidoc AmU||MARK
Stack marker variable for the XSUB.  See C<dMARK>.

=for apidoc Am|void|PUSHMARK|SP
Opening bracket for arguments on a callback.  See C<PUTBACK> and
L<perlcall>.

=for apidoc Ams||dSP
Declares a local copy of perl's stack pointer for the XSUB, available via
the C<SP> macro.  See C<SP>.

=for apidoc ms||djSP

Declare Just C<SP>. This is actually identical to C<dSP>, and declares
a local copy of perl's stack pointer, available via the C<SP> macro.
See C<SP>.  (Available for backward source code compatibility with the
old (Perl 5.005) thread model.)

=for apidoc Ams||dMARK
Declare a stack marker variable, C<mark>, for the XSUB.  See C<MARK> and
C<dORIGMARK>.

=for apidoc Ams||dORIGMARK
Saves the original stack mark for the XSUB.  See C<ORIGMARK>.

=for apidoc AmU||ORIGMARK
The original stack mark for the XSUB.  See C<dORIGMARK>.

=for apidoc Ams||SPAGAIN
Refetch the stack pointer.  Used after a callback.  See L<perlcall>.

=for apidoc Am|void|EXTEND|SP|int nitems
Used to extend the argument stack for an XSUB's return values. Once
used, guarantees that there is room for at least C<nitems> to be pushed
onto the stack.
