17.2.141. MPI_File_set_errhandler

MPI_File_set_errhandler - Sets the error handler for a file.

17.2.141.1. SYNTAX

17.2.141.1.1. C Syntax

#include <mpi.h>

int MPI_File_set_errhandler(MPI_File file, MPI_Errhandler
     errhandler)

17.2.141.1.2. Fortran Syntax

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

17.2.141.1.3. 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

17.2.141.2. INPUT/OUTPUT PARAMETER

  • file: File (handle).

17.2.141.3. INPUT PARAMETER

  • errhandler: New error handler for file (handle).

17.2.141.4. OUTPUT PARAMETER

  • IERROR: Fortran only: Error status (integer).

17.2.141.5. 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.

17.2.141.6. ERRORS

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.

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.
