Hello,
Please excuse my naivety, I'm trying to use NativeCall to interface a Perl6
program with a C library and I have a problem mapping a char ** argument.
The C function has this prototype:
void function(char **arg1, char **arg2);
I read that declaring a sub with Str rw parameters would do the trick:
sub test(Str $arg1 is rw, Str $arg2 is rw) is native('mylibrary') { * }
When I use the imported test function:
my Str ($arg1, $arg2);
test($arg1, $arg2);
say $arg1, $arg2;
what appears is just
(Str)(Str)
Obviously a C test program works fine with that library, so I guess I'm
just using the wrong NativeCall mapping.
Any hint?
