MPI_Win_set_errhandler -  Sets a window error handler


SYNOPSIS

       #include <mpi.h>
       int MPI_Win_set_errhandler(MPI_Win win,MPI_Errhandler errhdl)


INPUT PARAMETERS

       errhdl  - new error handler for window (handle) win - win­
       dow (handle)


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 For­
       tran, 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

       If an error occurs in an MPI  function,  the  current  MPI
       error  handler  is  called to handle it.  By default, this
       error handler aborts the MPI job.  The error  handler  may
       be  changed with MPI_Errhandler_set ; the predefined error
       handler MPI_ERRORS_RETURN may be used to cause error  val­
       ues  to  be returned (in C and Fortran; this error handler
       is less useful in with the C++ MPI bindings.   The  prede­
       fined error handler MPI::ERRORS_THROW_EXCEPTIONS should be
       used in C++ if the error value  needs  to  be  recovered).
       Note  that  MPI does not guarantee that an MPI program can
       continue past an error.

       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.  The C++  bind­
       ings  for  MPI  do not return error values; instead, error
       values are communicated by  throwing  exceptions  of  type
       MPI::Exception  (but not by default).  Exceptions are only
       thrown if the error value is not MPI::SUCCESS .

       Note that if the MPI::ERRORS_RETURN handler is set in C++,
       while  MPI functions will return upon an error, there will
       be no way to recover what the actual error value was.
       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_ERR_WIN
              - Invalid window.  A common error is to use a  null
              window in a call.

              -  Invalid  argument.  Some argument is invalid and
              is not identified by a specific error class.   This
              is typically a NULL pointer or other such error.
