INPUT PARAMETER
function User-defined error handling procedure (function).
OUTPUT PARAMETERS
errhandler
MPI error handler (handle).
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_Comm_create_errhandler creates an error handler that can be attached to communicators. This function is identical to MPI_Errhan-
dler_create, the use of which is deprecated.
In C, the user routine should be a function of type MPI_Comm_errhandler_fn, which is defined as
typedef void MPI_Comm_errhandler_fn(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. This
typedef replaces MPI_Handler_function, the use of which is deprecated.
In Fortran, the user routine should be of this form:
SUBROUTINE COMM_ERRHANDLER_FN(COMM, ERROR_CODE, ...)
INTEGER COMM, ERROR_CODE
In C++, the user routine should be of this form:
typedef void MPI::Comm::Errhandler_fn(MPI_Comm &, int *, ...);
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. 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.
