24=for apidoc AmU||SP
25Stack pointer. This is usually handled by C<xsubpp>. See C<dSP> and
26C<SPAGAIN>.
27
28=for apidoc AmU||MARK
29Stack marker variable for the XSUB. See C<dMARK>.
30
31=for apidoc Am|void|PUSHMARK|SP
32Opening bracket for arguments on a callback. See C<PUTBACK> and
33L<perlcall>.
34
35=for apidoc Ams||dSP
36Declares a local copy of perl's stack pointer for the XSUB, available via
37the C<SP> macro. See C<SP>.
38
39=for apidoc ms||djSP
40
41Declare Just C<SP>. This is actually identical to C<dSP>, and declares
42a local copy of perl's stack pointer, available via the C<SP> macro.
43See C<SP>. (Available for backward source code compatibility with the
44old (Perl 5.005) thread model.)
45
46=for apidoc Ams||dMARK
47Declare a stack marker variable, C<mark>, for the XSUB. See C<MARK> and
48C<dORIGMARK>.
49
50=for apidoc Ams||dORIGMARK
51Saves the original stack mark for the XSUB. See C<ORIGMARK>.
52
53=for apidoc AmU||ORIGMARK
54The original stack mark for the XSUB. See C<dORIGMARK>.
55
56=for apidoc Ams||SPAGAIN
57Refetch the stack pointer. Used after a callback. See L<perlcall>.

172onto the stack.
173
174=for apidoc Am|void|PUSHs|SV* sv
