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).
