MPI_Win_create_errhandler(3)       Open MPI       MPI_Win_create_errhandler(3)



NAME
       MPI_Win_create_errhandler - Creates an error handler for a window.


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Win_create_errhandler(MPI_Win_errhandler_fn *function,
            MPI_Errhandler *errhandler)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_WIN_CREATE_ERRHANDLER(FUNCTION, ERRHANDLER, IERROR)
            EXTERNAL FUNCTION
            INTEGER ERRHANDLER, IERROR


C++ Syntax
       #include <mpi.h>
       static MPI::Errhandler MPI::Win::Create_errhandler(MPI::Win::
            Errhandler_fn* function)


INPUT PARAMETER
       function  User-defined error-handling procedure (function).


OUTPUT PARAMETERS
       errhandler
                 MPI error handler (handle).

       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       MPI_Win_create_errhandler should be, in C, a function of type
       MPI_Win_errhandler_fn, which is defined as

       typedef void MPI_Win_errhandler_fn(MPI Win *, int *, ...);

       The first argument is the window in use, the second is the error code
       to be returned.

       In Fortran, the user routine should be of the form:

       SUBROUTINE WIN_ERRHANDLER_FN(WIN, ERROR_CODE, ...)
           INTEGER WIN, ERROR_CODE

       In C++, the user routine should be of the form:

       typedef void MPI::Win::Errhandler_fn(MPI::Win &, int *, ...);


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.
