DESCRIPTION
       MPICommaccept establishes communication with a client. It is  collec-
       tive  over  the  calling  communicator. It returns an intercommunicator
       that allows communication with the client, after the  client  has  con-
       nected  with  the  MPICommaccept  function using the MPICommconnect
       function.

       The  portname  must  have  been  established   through   a   call   to
       MPIOpenport on the root.



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.

       See the MPI man page for a full list of MPI error codes.
