.SH DESCRIPTION
|
|
.ft R
|
|
MPI_Win_create_errhandler should be, in C, a function of type MPI_Win_errhandler_fn, which is defined as
|
|
.sp
|
|
.nf
|
|
typedef void MPI_Win_errhandler_fn(MPI Win *, int *, ...);
|
|
.fi
|
|
.sp
|
|
The first argument is the window in use, the second is the error code to be returned.
|
|
.sp
|
|
In Fortran, the user routine should be of the form:
|
|
.sp
|
|
.nf
|
|
SUBROUTINE WIN_ERRHANDLER_FN(WIN, ERROR_CODE, ...)
|
|
INTEGER WIN, ERROR_CODE
|
|
.fi
|
|
.sp
|
|
In C++, the user routine should be of the form:
|
|
.sp
|
|
.nf
|
|
typedef void MPI::Win::Errhandler_fn(MPI::Win &, int *, ...);
|
|
.fi
|
|
|
|
.SH 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.
|
|
.sp
|
|
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.
