This call should return true if it could set the name and/or the type Sets address to the address of the dynamic type if value_type is set to a file or load address.

Sets local_buffer to a buffer containing the data of the dynamic type if value_type is set to a host address. Callers should copy local_buffer over into their own buffer if they want to keep the data alive.
