Re: Linking Open Perl Filehandles to Stream Based C code via XS

[beauregard]

I've had luck with something along the lines of:

XS(XS_widget)
{
    dXSARGS;

    FILE* in = PerlIO_findFILE(IoIFP(sv_2io(ST(0))));
    FILE* out = PerlIO_findFILE(IoIFP(sv_2io(ST(1))));

    /* copy in to out */
}

Obviously you'd want to do stuff like error handling and arg counts and stuff, but that's basically how xsubpp handles XSUB definitions like the following in .xs files:

char*
read(fd,count)
   FILE* fd
   int count
  CODE:
   ...

c.

Thanks very much, that's just what I was after.
