In that case it's a pointer to a pointer: since in C a function can't multiple values, when one wants to return two strings, one needs to use several char ** arguments in the function call. The caller passes a reference to a pointer and the function returns the address of a malloc-ed memory area with a return string in it.
When I write a C program I'm able to call that function and I receive the strings, so I guess my problem is just a mapping one.
