The receive_* functions do some kind of
unmarshaling/unserialization. I.e. they read bytes of a byte stream
and interpret them as a 16bit unsigned int for example. Or a
string. Or an event type. Each receive_* function mallocs a struct,
fills the from the byte stream gather values into the struct and
returns this struct.
