ctypes docs should mention that Structures can be passed with byref() to functions expecting pointer to mutable memory without explicit allocation of mutable memory block with create_string_buffer() or similar function.

I think not only Structures but also other ctypes can be passed with byref() to functions expecting pointer to mutable memory.

This is a not a bug, it asks for parameter types to explained. API documentation reference should provide the guidance.
