MPI_Errhandler_create - Creates an MPI-style error handler -- use of this routine is deprecated.
int MPI_Errhandler_create(MPI_Handler_function *function,
MPI_ERRHANDLER_CREATE(FUNCTION, ERRHANDLER, IERROR)
INTEGER ERRHANDLER, IERROR
function User-defined error handling procedure.
MPI error handler (handle).
IERROR Fortran only: Error status (integer).
Note that use of this routine is deprecated as of MPI-2. Please use MPI_Comm_create_errhandler instead.
This deprecated routine is not available in C++.
Registers the user routine function for use as an MPI exception handler. Returns in errhandler a handle to the registered exception han-
In the C language, the user routine should be a C function of type MPI_Handler_function, which is defined as
typedef void (MPI_Handler_function)(MPI_Comm *, int *, ...);
The first argument is the communicator in use. The second is the error code to be returned by the MPI routine that raised the error. If the
routine would have returned MPI_ERR_IN_STATUS, it is the error code returned in the status for the request that caused the error handler to
be invoked. The remaining arguments are stdargs arguments whose number and meaning is implementation-dependent. An implementation should
clearly document these arguments. Addresses are used so that the handler may be written in Fortran.
The MPI-1 Standard states that an implementation may make the output value (errhandler) simply the address of the function. However, the
action of MPI_Errhandler_ free makes this impossible, since it is required to set the value of the argument to MPI_ERRHANDLER_NULL. In
addition, the actual error handler must remain until all communicators that use it are freed.
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. By default, this error handler aborts the MPI job, except for
I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be
used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
