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 :(
