  !***PURPOSE  Return unit number(s) to which error messages are being
         ! sent.
  !***LIBRARY   SLATEC (XERROR)

  !***DESCRIPTION
  !
  ! Abstract
  !    XGETUA may be called to determine the unit number or numbers
  !    to which error messages are being sent.
  !    These unit numbers may have been set by a CALL to XSETUN,
  !    or a CALL to XSETUA, or may be a default value.
  !
  ! Description of Parameters
  !  --Output--
  !    IUNIT - an array of one to five unit numbers, depending
  !            on the value of N.  A value of zero refers to the
  !            default unit, as defined by the I1MACH machine
  !            constant routine.  Only IUNIT(1),...,IUNIT(N) are
  !            defined by XGETUA.  The values of IUNIT(N+1),...,
  !            IUNIT(5) are not defined (for N .LT. 5) or altered
  !            in any way by XGETUA.
  !    N     - the number of units to which copies of the
  !            error messages are being sent.  N will be in the
  !            range from 1 to 5.
