       name      A  unique  specifier  for  the actual (as opposed to virtual)
                 node.

       resultlen Length (in characters) of result returned in name.

       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       This routine returns the name of the processor on which it  was  called
       at  the  moment of the call. The name is a character string for maximum
       flexibility. From this value it must be possible to identify a specific
       piece  of hardware. The argument name must represent storage that is at
       least MPIMAXPROCESSORNAME characters long.

       The number of characters actually written is  returned  in  the  output
       argument, resultlen.


NNOOTTEESS
       The  user  must  provide at least MPIMAXPROCESSORNAME space to write
       the processor name; processor names can be this long. The  user  should
       examine  the output argument, resultlen, to determine the actual length
       of the name.



EERRRROORRSS
       Almost all MPI routines return an error value; C routines as the  value
       of  the  function  and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default  error  handler  is  set  to
       MPI::ERRORSTHROWEXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.

       Before the error value is returned, the current MPI  error  handler  is
       called.  By  default, this error handler aborts the MPI job, except for
       I/O  function  errors.  The  error  handler   may   be   changed   with
       MPICommseterrhandler; the predefined error handler MPIERRORSRETURN
       may be used to cause error values to be returned. Note  that  MPI  does
       not guarantee that an MPI program can continue past an error.
