NAME

       MPI_File_set_errhandler  - Sets the error handler for a file.

SYNTAX

C Syntax

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

Fortran Syntax

       USE MPI
       ! or the older form: INCLUDE 'mpif.h'
       MPI_FILE_SET_ERRHANDLER(FILE, ERRHANDLER, IERROR)
            INTEGER   FILE, ERRHANDLER, IERROR

Fortran 2008 Syntax

       USE mpi_f08
       MPI_File_set_errhandler(file, errhandler, ierror)
            TYPE(MPI_File), INTENT(IN) :: file
            TYPE(MPI_Errhandler), INTENT(IN) :: errhandler
            INTEGER, OPTIONAL, INTENT(OUT) :: ierror

C++ Syntax

       #include <mpi.h>
       void MPI::File::Set_errhandler(const MPI::Errhandler& errhandler)

INPUT/OUTPUT PARAMETER

       file      File (handle).

INPUT PARAMETER

       errhandler
                 New error handler for file (handle).

OUTPUT PARAMETER

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       Attaches a new error handler to a file. The error handler must be either a predefined error handler or an
       error handler created by a call to MPI_File_create_errhandler.

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.
