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'

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.
