Actually, I think you send it into C-code as a HArrayOfString *.
Then you unhand it, and can reference the body field, which will be a
HString *. HString is a typedef of Hjava_lang_String, which is a
java String instance.
So, in your code you say:
HArrayOfString *Hstrings;
for (i = 0; i < n; i++) {
char *str = <some null terminated C string>;
unhand(Hstrings)->body[i] = makeJavaString(str, strlen(str));
}
