MPI_Comm_f2c(3)
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.

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).
