call_pv on CORE:: sub from XS

OlegG has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to do this
call_pv("CORE::socketpair", G_SCALAR);
And this works excellent on perl 5.20, but fails on perl 5.14 with message "Undefined subroutine &CORE::socketpair called".

So, is there a way to make such a thing on older perl?

Yes, also tried this. No success: "Undefined subroutine &main::socketpair called" Well then, something you're leaving out :) As http://perl5.git.perl.org/perl.git/blob/a35ef416833511da752c4b5b836b7a8915712aab:/XSUB.h#l609 defines socketpair, so try just calling socketpair() (or my_socketpair() ) instead of call_pv-ing it Or try call-pv-ing notxs :) `sub notxs { my $Rdr; my $Wt; use Socket; socketpair($Rdr, $Wtr, AF_UNIX, SOCK_STREAM, PF_UNSPEC); return $Rdr, $Wtr; }` [download]	[reply] [d/l]
