MPI_Group_f2c(3)

NAME
MPI_Group_f2c - Convert a group handle from its Fortran representation to its C representation

SYNOPSIS
#include <mpi.h>
MPI_Group
MPI_Group_f2c(MPI_Fint f_handle)

INPUT PARAMETER
f_handle
    - Fortran group handle

RETURN VALUE
group
    - C group 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.
