[Mono-dev] Marshalling C-strings that need to be g_free()d

[Jon Shemitz]

Sorry for the newbie question, but my Windows .NET experience doesn't
help me here, nor does MonoDoc or Google. (I'm sure I just don't know
how to ask the right questions, yet, as this must be a FAQ):

If I have a C function like

void caller_owns_string(char** out_string);

How do I tell PInvoke that I 'own' the returned UTF8 string, and that
the marshaller needs to g_free() *out_string after converting it to
System.String?
