Outputs each arg to the binary output port port using the same interpretations as bytestring, but without creating any bytevectors. The args are validated before any bytes are written to port; if they are ill-formed, an error satisfying bytestring-error? is raised.

(call-with-port (open-output-bytevector)
                (lambda (port)
                  (write-binary-bytestring port #\Z #x61 #x70 "hod")
                  (get-output-bytevector port)))
  ⇒ #u8"Zaphod"
