NAME¶
MPI_File_get_errhandler - Gets the error handler for a file.
C Syntax¶
#include <mpi.h>
int MPI_File_get_errhandler(MPI_File file, MPI_Errhandler
*errhandler)
Fortran Syntax¶
INCLUDE 'mpif.h'
MPI_FILE_GET_ERRHANDLER(FILE, ERRHANDLER, IERROR)
INTEGER FILE, ERRHANDLER, IERROR
C++ Syntax¶
#include <mpi.h>
MPI::Errhandler MPI::File::Get_errhandler() const
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.
