IERROR Fortran only: Error status (integer).
DESCRIPTION
This routine associates an error string with an error code or class.
Calling MPI_Add_error_string for an error code or class that already
has an associated error string will replace the old string with the new
one. It is erroneous to call MPI_Add_error_string for an error value
not generated via MPI_Add_error_class or MPI_Add_error_code (e.g., an
error code or class with a value not greater than MPI_LAST_ERRCODE).
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++ func‐
tions 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.
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for
I/O function errors. The error handler may be changed with
MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN
may be used to cause error values to be returned. Note that MPI does
not guarantee that an MPI program can continue past an error.
