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_function *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_function* function)

DEPRECATED TYPE NAME NOTE

       MPI-2.2 deprecated the MPI_Win_errhandler_fn and MPI::Win::Errhandler_fn types in favor of
       MPI_Win_errhandler_function and  MPI::Win::Errhandler_function,  respectively.   Open  MPI
       supports both names (indeed, the _fn names are typedefs to the _function names).

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_function,
       which is defined as

       typedef void MPI_Win_errhandler_function(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_FUNCTION(WIN, ERROR_CODE, ...)
           INTEGER WIN, ERROR_CODE

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

       typedef void MPI::Win::errhandler_function(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_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.
