Hello,
I've seen this posted before, but I'm not sure what the answer is.
I have an XS interface to a 'C' library, which I used h2xs to create.
One of the functions takes argc & argv parameters. The h2xs created
argv as a char **, which is obviously correct. When I run make test
which is loading the module, it dies because XS_unpack_PtrPtr() is
undefined. I see the typemap file in ExtUtils is defining char ** as
a T_PACKEDARRAY and so XS_unpack_$ntype($arg) gets created. Where is
this? Is it a function or a macro? Do I need to implement it? I saw
the posting to packing a char ** on to the stack. Do I need to do the
opposite?
Thank You,
STH
