OUTPUT PARAMETERS
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_Win_complete is a one-sided MPI communication synchronization call,
completing an RMA access epoch on win started by a call to
MPI_Win_start. MPI_Win_complete enforces the completion of preceding
RMA calls at the origin and not at the target. A put or accumulate call
may not have completed at the target when it has completed at the ori-
gin.
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_Win_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.
