17.2.156.2. Input/Output Parameter

fh : File handle (handle).

17.2.156.3. Input Parameter

buf : Initial address of buffer (choice).

17.2.156.4. Output Parameters

status : Status object (status).
IERROR : Fortran only: Error status (integer).

17.2.156.5. Description

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.

17.2.156.6. Notes

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.

17.2.156.7. Errors

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.

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.
