ERROR(5)                                                 ERROR(5)

     NAME
          error - return an error

     SYNOPSIS
          size[4] Rerror tag[2] ename[s]

     DESCRIPTION
          The Rerror message (there is no Terror) is used to return an
          error string describing the failure of a transaction.  It
          replaces the corresponding reply message that would accom-
          pany a successful call; its tag is that of the failing
          request.

          By convention, clients may truncate error messages after 128
          bytes, defined as the constant Sys->ERRMAX.
