17.2.106. MPI_File_get_errhandler

MPI_File_get_errhandler - Gets the error handler for a file.

17.2.106.1. SYNTAX

17.2.106.1.1. C Syntax

#include <mpi.h>

int MPI_File_get_errhandler(MPI_File file, MPI_Errhandler
     *errhandler)

17.2.106.1.2. Fortran Syntax

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

17.2.106.1.3. Fortran 2008 Syntax

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

17.2.106.2. INPUT PARAMETER

  • file: File (handle).

17.2.106.3. OUTPUT PARAMETERS

  • errhandler: MPI error handler currently associated with file (handle).

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

17.2.106.4. DESCRIPTION

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

17.2.106.5. 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.
