Just like in C. You need to create a pointer to a char array and store that. Which means you need to allocate some bytes (ExternalAddress allocate: byteSize + 1), copy your string there (byteAt:put:), add a terminating 0 byte, then store the address of that in your struct. Be sure to free the memory allocated when you're done.

I think there used to be a helper function for that but I can't find it (only found fromCString).
