NAME¶
MPI_Win_complete - Completes an RMA access epoch on win started by
a call to MPI_Win_start
C Syntax¶

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
- 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.
