  25 /*  FUNCTION
  26         Writes one big endian 16bit value to a streamhook.
  27
  28     INPUTS
  29         hook - Write to this streamhook
  30         data - Data to be written
  31         stream - Stream passed to streamhook
  32
  33     RESULT
  34         The function returns TRUE on success and FALSE otherwise.
  35         See IoErr() for the reason in case of an error.

  38         This function writes big endian values to a file even on little
  39         endian machines.
