MPI_Group_f2c - Convert a group handle from its Fortran representation
to its C representation
- Fortran group handle
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
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.
For more information, please see the official MPI Forum web site, which
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).
