in reply to How to make thread-save data on C API

See SvSHARE(), SvLOCK & SvUNLOCK in perlapi.

Alternatively, you might do:

use threads; use threads::shared; my $d : shared; $d = shared_clone( mymodule::myfunc() );

    Thanks for the info. Unfortunately, the SvSHARE does not work for me - I always receive empty HASHREF:
    rt = newHV(); SvSHARE((SV*)rt); sv = newSViv(42); //SvSHARE(sv); hv_stores(rt, "fe", sv); ... ST(i) = sv_2mortal((SV*)newRV_noinc((SV*)rt)); XSRETURN(4); --- result for this tuple: $VAR1 = {};
    So, I have shared HASH, but without any contents inside hash... I'll use shared_clone, but I think I can reproduce/clone the shared_clone source code...

      No. I can't make it work either :(
