  45     Sets the current Preferences structure.
  46
  47     INPUTS
  48     prefbuffer - The buffer which contains your settings for the
  49         preferences.
  50     size - The number of bytes of the buffer you want to be copied.
  51     inform - If TRUE, all windows with IDCMP_NEWPREFS IDCMPFlags set
  52         get an IDCMP_NEWPREFS message.
  53
  54     RESULT
  55     Returns your parameter buffer.
