DESCRIPTION
MPI_Comm_create_errhandler creates an error handler that can be attached to communicators. This func-tion function
tion is identical to MPI_Errhandler_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 depre-cated. deprecated.
cated.
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++ 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. 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.
