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++ func-
tions 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.
