NAME

       MPI_Win_set_errhandler -  Set window error handler

SYNOPSIS

       int MPI_Win_set_errhandler(MPI_Win win, MPI_Errhandler errhandler)

INPUT PARAMETERS

       win    - window (handle)
       errhandler
	      - new error handler for window (handle)

THREAD AND INTERRUPT SAFETY

       This  routine is thread and interrupt safe only if no MPI routine that updates or frees the same MPI object may be called concurrently with
       this routine.

       The MPI standard defined a thread-safe interface but this does not mean that all routines may be called	without  any  thread  locks.   For
       example,  two  threads  must  not attempt to change the contents of the same MPI_Info object concurrently.  The user is responsible in this
       case for using some mechanism, such as thread locks, to ensure that only one thread at a time makes use of this routine.

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
