MPI_File_write_ordered_end - Writes a file at a location specified
by a shared file pointer; ending part of a split collective routine (blocking).
C Syntax#include <mpi.h> int MPI_File_write_ordered_end(MPI_File fh, const
void *buf, MPI_Status *status)
USE MPI
! or the older form: INCLUDE ’mpif.h’
MPI_FILE_WRITE_ORDERED_END(FH, BUF, STATUS, IERROR)
<type> BUF(*)
INTEGER FH, STATUS(MPI_STATUS_SIZE), IERROR
#include <mpi.h>
void MPI::File::Write_ordered_end(const void* buf, MPI::Status& status)
void MPI::File::Write_ordered_end(const void* buf)
- fh
- File handle (handle).
- buf
- Initial
address of buffer (choice).
- status
- Status object (status).
- IERROR
- Fortran only: Error status (integer).
MPI_File_write_ordered_end
is the ending part of a split collective routine that must be called by
all processes in the communicator group associated with the file handle
fh. MPI_File_write_ordered_end returns the number of elements written into
the file associated with fh in status.
All the nonblocking collective
routines for data access are "split" into two routines, each with _begin
or _end as a suffix. These split collective routines are subject to the
semantic rules described in Section 9.4.5 of the MPI-2 standard.
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. For MPI I/O function errors, the default error handler is set
to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler;
the predefined error handler MPI_ERRORS_ARE_FATAL may be used to make I/O
errors fatal. Note that MPI does not guarantee that an MPI program can continue
past an error.
