SYNTAX

C Syntax

#include <mpi.h>
int MPI_File_get_errhandler(MPI_File file, MPI_Errhandler 
        *errhandler)

Fortran Syntax

INCLUDE 'mpif.h'
MPI_FILE_GET_ERRHANDLER(FILE, ERRHANDLER, IERROR)
        INTEGER FILE, ERRHANDLER, IERROR 

C++ Syntax

MPI::Errhandler MPI::File::Get_errhandler() const

INPUT PARAMETER

file
File (handle).

OUTPUT PARAMETERS

errhandler
MPI error handler currently associated with file (handle).
IERROR
Fortran only: Error status (integer).

DESCRIPTION

Returns in errhandler (a handle to) the error handler that is currently associated with file file.

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.

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.
