MPI_Win_get_errhandler(3OpenMPI)                                            MPI_Win_get_errhandler(3OpenMPI)



NAME
       MPI_Win_get_errhandler - Retrieves the error handler currently associated with a window.


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Win_get_errhandler(MPI_Win win, MPI_Errhandler *errhandler)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_WIN_GET_ERRHANDLER(WIN, ERRHANDLER, IERROR)
            INTEGER WIN, ERRHANDLER, IERROR


C++ Syntax
       #include <mpi.h>
       MPI::Errhandler MPI::Win::Get_errhandler() const


INPUT PARAMETER
       win       Window (handle).


OUTPUT PARAMETERS
       errhandler
                 Error handler currently associated with window (handle).

       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       MPI_Win_get_errhandler retrieves the error handler currently associated with a window.


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_Comm_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.
