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
USE MPI ! or the older form: INCLUDE 'mpif.h' MPI_WIN_CREATE_ERRHANDLER(FUNCTION, ERRHANDLER, IERROR) EXTERNAL FUNCTION INTEGER ERRHANDLER, IERROR
Fortran 2008 Syntax
USE mpi_f08 MPI_Win_create_errhandler(win_errhandler_fn, errhandler, ierror) PROCEDURE(MPI_Win_errhandler_function) :: win_errhandler_fn TYPE(MPI_Errhandler), INTENT(OUT) :: errhandler INTEGER, OPTIONAL, INTENT(OUT) :: 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.
