C synopsis

#include <mpi.h>
MPI_Group MPI_Group_f2c(MPI_Fint group);

Parameters

group

is the group (handle) (IN)

Description

This function does not have C++ or FORTRAN bindings. MPI_Group_f2c returns a C handle to a group. If group is a valid FORTRAN handle to a group, MPI_Group_f2c returns a valid C handle to that same group. If group is set to the FORTRAN value MPI_GROUP_NULL, MPI_Group_f2c returns the equivalent null C handle. If group is not a valid FORTRAN handle, MPI_Group_f2c returns a non-valid C handle. The converted handle is returned as the function's value. There is no error detection or return code.

Errors

None.
