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).

#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

USE mpi_f08
MPI_File_write_ordered_end(fh, buf, status, ierror)
	TYPE(MPI_File), INTENT(IN) :: fh
	TYPE(*), DIMENSION(..), INTENT(IN), ASYNCHRONOUS :: buf
	TYPE(MPI_Status) :: status

#include <mpi.h>
void MPI::File::Write_ordered_end(const void* buf, MPI::Status& status)
void MPI::File::Write_ordered_end(const void* buf)

File handle (handle).

Initial address of buffer (choice).

Status object (status).
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.
