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 origin.
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_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.
