Hi Jin,
I don’t think you can access perl variables this way because your C function
needs some sort of reference to them. Change your code to,
$data = "this is a test";
test($data);
use Inline C => <<'END_OF_C_CODE';
void test(SV* data) {
printf("here: %s\n", SvPV(data, PL_na));
}
END_OF_C_CODE
Cheers,
Ron.
