NAME

       MPI_Win_get_errhandler -  Get the error handler for the MPI RMA window

SYNOPSIS

       int MPI_Win_get_errhandler(MPI_Win win, MPI_Errhandler *errhandler)

INPUT PARAMETERS

       win    - window (handle)

OUTPUT PARAMETERS

       errhandler
              - error handler currently associated with window (handle)

THREAD AND INTERRUPT SAFETY

       This  routine  is  thread-safe.   This  means  that this routine may be
       safely used by multiple threads without the need for any  user-provided
       thread  locks.  However, the routine is not interrupt safe.  Typically,
       this is due to the use of memory allocation routines such as malloc  or
       other  non-MPICH  runtime  routines  that are themselves not interrupt-
       safe.

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK )  have
       an  additional  argument ierr at the end of the argument list.  ierr is
       an integer and has the same meaning as the return value of the  routine
       in  C.   In Fortran, MPI routines are subroutines, and are invoked with
       the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in
       Fortran.

ERRORS

       All  MPI  routines  (except  MPI_Wtime  and MPI_Wtick ) return an error
       value; C routines as the value of the function and Fortran routines  in
       the last argument.  Before the value is returned, the current MPI error
       handler is called.  By default, this error handler aborts the MPI  job.
       The  error  handler  may  be  changed with MPI_Comm_set_errhandler (for
       communicators),    MPI_File_set_errhandler     (for     files),     and
       MPI_Win_set_errhandler   (for   RMA   windows).    The   MPI-1  routine
       MPI_Errhandler_set  may  be  used  but  its  use  is  deprecated.   The
       predefined  error  handler MPI_ERRORS_RETURN may be used to cause error
       values to be returned.  Note that MPI does not guarentee  that  an  MPI
       program  can  continue past an error; however, MPI implementations will
       attempt to continue whenever possible.

       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_ERR_WIN
              - Invalid MPI window object
       MPI_ERR_OTHER
              - Other error; use  MPI_Error_string  to  get  more  information
              about this error code.
