4.13.3. Error Handlers for Files

MPI_FILE_CREATE_ERRHANDLER(function, errhandler)
[ IN function] user defined error handling procedure (function)
[ OUT errhandler] MPI error handler (handle)

int MPI_File_create_errhandler(MPI_File_errhandler_fn *function, MPI_Errhandler *errhandler)

MPI_FILE_CREATE_ERRHANDLER(FUNCTION, ERRHANDLER, IERROR)
EXTERNAL FUNCTION
INTEGER ERRHANDLER, IERROR

static MPI::Errhandler MPI::File::Create_errhandler(MPI::File::Errhandler_fn* function)

The user routine should be, in C, a function of type MPI_File_errhandler_fn, which is defined as

typedef void MPI_File_errhandler_fn(MPI_File *, int *, ...);

The first argument is the file in use, the second is the error code to be returned.

In Fortran, the user routine should be of the form:

SUBROUTINE FILE_ERRHANDLER_FN(FILE, ERROR_CODE, ... )
INTEGER FILE, ERROR_CODE

In C++, the user routine should be of the form:

typedef void MPI::File::Errhandler_fn(MPI::File &, int *, ... );

MPI_FILE_SET_ERRHANDLER(file, errhandler)
[ INOUT file] file (handle)
[ IN errhandler] new error handler for file (handle)

int MPI_File_set_errhandler(MPI_File file, MPI_Errhandler errhandler)

MPI_FILE_SET_ERRHANDLER(FILE, ERRHANDLER, IERROR)
INTEGER FILE, ERRHANDLER, IERROR

void MPI::File::Set_errhandler(const MPI::Errhandler& errhandler)

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.

MPI_FILE_GET_ERRHANDLER(file, errhandler)
[ IN file] file (handle)
[ OUT errhandler] error handler currently associated with file (handle)

int MPI_File_get_errhandler(MPI_File file, MPI_Errhandler *errhandler)

MPI_FILE_GET_ERRHANDLER(FILE, ERRHANDLER, IERROR)
INTEGER FILE, ERRHANDLER, IERROR

MPI::Errhandler MPI::File::Get_errhandler() const

Retrieves the error handler currently associated with a file.
