MPI::Errhandler MPI::File::Get_errhandler() const
- file
- File (handle).
- errhandler
- MPI error
handler currently associated with file (handle).
- IERROR
- Fortran only: Error
status (integer).
Returns in errhandler (a handle to) the error
handler that is currently associated with file file.
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.
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.
