NAME

       MPI_Win_complete - Completes an RMA access epoch on win started by a call to MPI_Win_start

SYNTAX

C Syntax

       #include <mpi.h>
       MPI_Win_complete(MPI_Win win)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_WIN_COMPLETE(WIN, IERROR)

C++ Syntax

       #include <mpi.h>
       void MPI::Win::Complete() const

INPUT PARAMETERS

       win       Window object (handle).

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 origin.

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_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.
