Hi, I am new to perlXS. I am using perl XS(http://perldoc.perl.org/perlguts.html). and writing perl wrapper over my C++ code. I want to return a value of type int64_t from C++ to perl. Please see my code snippet. But it is truncating the value.(of course while compiling itself I am getting this Warning: Conversion of 64 bit type value to "long" causes truncation). In documentation I do not find any information on how to send int64_t (or long) values. Please tell me what i can do here. Thanks in advance D. L. Kumar 
SV* get()
{
   int64_t val = ..;
   if (...){
       return &PL_sv_undef;
   }
   return newSViv(val);
}
