.SH DESCRIPTION
|
|
.ft R
|
|
MPI_File_get_group returns a duplicate of the group of the communicator
|
|
used to open the file associated with
|
|
.I fh.
|
|
The group is returned in
|
|
.I group.
|
|
The user is responsible for freeing
|
|
.I group,
|
|
using MPI_Group_free.
|
|
|
|
.SH ERRORS
|
|
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI:Exception object.
|
|
.sp
|
|
Before the error value is returned, the current MPI error handler is
|
|
called. For MPI I/O function errors, the default error handler is set to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error.
