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_fn *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_fn* function)
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_fn, which is defined astypedef void MPI_Win_errhandler_fn(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_FN(WIN, ERROR_CODE, ...) INTEGER WIN, ERROR_CODE
In C++, the user routine should be of the form:
typedef void MPI::Win::Errhandler_fn(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_Comm_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.
