  25   23  **
  26   24  **      Assigned 'str' to a "fake" file pointer. This allows common
  27   25  **      o/p formatting function sm_vprintf() to be used.
  28   26  **

  29   27  **      Parameters:
  30   28  **              str -- location for output
  31   29  **              n -- maximum size for o/p
  32   30  **              fmt -- format directives
  33   31  **              ap -- data unit vectors for use by 'fmt'
  34   32  **
  35   33  **      Results:
  36   34  **              result from sm_io_vfprintf()
  37   35  **
  38   36  **      Side Effects:
  39   37  **              Limits the size ('n') to INT_MAX.
