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

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