man MPI_Comm_c2f (Fonctions bibliothèques) - Convert a communicator handle from its C representation to its Fortran representation

NAME

MPI_Comm_c2f - Convert a communicator handle from its C representation to its Fortran representation

SYNOPSIS

#include <mpi.h>
MPI_Fint
MPI_Comm_c2f(MPI_Comm comm)

INPUT PARAMETER

comm
- C communicator handle

RETURN VALUE

f_handle
- Fortran 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.
