NAME

MPI_Comm_c2f - Convert a C MPI communicator into a FORTRAN MPI communicator

SYNOPSIS

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

#include <pmpi.h> MPI_Fint PMPI_Comm_c2f(MPI_Comm comm );

INPUT PARAMETER

comm - communicator handle from C (handle)

RETURN VALUE

FORTRAN communicator handle (handle)

DESCRIPTION

The MPI_Comm_c2f() function is used to convert a C communicator handle comm , into a FORTRAN integer-sized communicator handle. This function will never raise an error.

Since this function is compiled inline for performance reasons, a profiler will not be able to hook it. (In this MPI implementation, the C and FORTRAN handles are identical for this type of handle.) PMPI_Comm_f2c() is the profiling version of this function.
