NAME

       MPI_Comm_f2c  -   Convert  a  communicator handle from its Fortran representation to its C
       representation

SYNOPSIS

       #include <mpi.h>
       MPI_Comm
       MPI_Comm_f2c(MPI_Fint f_handle)

INPUT PARAMETER

       f_handle
              - Fortran communicator handle

RETURN VALUE

       comm   - C communicator handle

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME  and  MPI_WTICK  )  have  an  additional
       argument  ierr  at  the  end  of  the  argument list.  ierr is an integer and has the same
       meaning as the  return  value  of  the  routine  in  C.   In  Fortran,  MPI  routines  are
       subroutines, and are invoked with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       This function does not return the normal MPI_SUCCESS integer value upon success.  Instead,
       it returns a handle to the converted object.  If an error  occurs,  the  appropriate  NULL
       handle will be returned.

MORE INFORMATION

       For  more information, please see the official MPI Forum web site, which contains the text
       of both the MPI-1 and MPI-2 standards.  These documents contain detailed information about
       each MPI function (most of which is not duplicated in these man pages).
