MPI_File_write_ordered_end(3OpenMPI)                                    MPI_File_write_ordered_end(3OpenMPI)



NAME
       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).


SYNTAX
       C Syntax
           #include <mpi.h>
           int MPI_File_write_ordered_end(MPI_File fh, void *buf,
                  MPI_Status *status)

       Fortran Syntax
           INCLUDE 'mpif.h'
           MPI_FILE_WRITE_ORDERED_END(FH, BUF, STATUS, IERROR)
                 <type>         BUF(*)
                 INTEGER        FH, STATUS(MPI_STATUS_SIZE), IERROR


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

       void MPI::File::Write_ordered_end(const void* buf)


INPUT/OUTPUT PARAMETER
       fh        File handle (handle).


INPUT PARAMETER
       buf       Initial address of buffer (choice).


OUTPUT PARAMETERS
       status    Status object (status).

       IERROR    Fortran only: Error status (integer).


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.


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.


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.  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.
