MPI_Comm_test_inter(3)

NAME
     MPI_Comm_test_inter - Tests to determine if a communicator is an
     intercommunicator

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Comm_test_inter ( comm, flag )
          MPI_Comm  comm;
          int      *flag;


     C++:

          #include <mpi.h>

          bool Comm::Is_inter() const


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER comm, ierror
          LOGICAL flag

          CALL MPI_COMM_TEST_INTER(comm, flag, ierror)


STANDARDS
     This release implements the MPI 1.2 standard, as documented by the MPI
     Forum in the spring 1997 release of MPI:  A Message Passing Interface
     Standard.

DESCRIPTION
     The MPI_Comm_test_inter routine tests to determine if a communicator is
     an intercommunicator.  This routine accepts the following parameters:

     comm      Specifies the communicator (handle)

     flag      Returns a value of true if the operation is completed (logical)

     ierror    Specifies the return code value for successful completion,
               which is in MPI_SUCCESS.  MPI_SUCCESS is defined in the mpif.h
               file.
