NAME

       MPI_File_get_errhandler  - Gets the error handler for a file.

SYNTAX

C Syntax

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

Fortran Syntax

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

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

C++ Syntax

       #include <mpi.h>
       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.
