NAME
       MMPPIIFFiilleewwrriitteeoorrddeerreeddeenndd - Writes a file at a location specified by a
       shared file pointer; ending part of a split collective routine  (block-
       ing).

DESCRIPTION
       MPIFilewriteorderedend  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.  MPIFilewriteorderedend returns
       the number of elements written into the file associated with fh in sta-
       tus.


NNOOTTEESS
       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 Sec-
       tion 9.4.5 of the MPI-2 standard.


EERRRROORRSS
       Almost all MPI routines return an error value; C routines as the  value
       of  the  function  and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default  error  handler  is  set  to
       MPI::ERRORSTHROWEXCEPTIONS, 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  MPIERRORSRETURN.  The  error  handler   may   be   changed   with
       MPIFileseterrhandler;      the      predefined     error     handler
       MPIERRORSAREFATAL may be used to make I/O errors  fatal.  Note  that
       MPI  does not guarantee that an MPI program can continue past an error.
