NAME

       MPI_File_write_at_all_end  - Writes a file at explicitly specified offsets; ending part of
       a split collective routine (blocking).

SYNTAX

C Syntax

       #include   <mpi.h>   int   MPI_File_write_at_all_end(MPI_File   fh,   const   void   *buf,
            MPI_Status *status)

Fortran Syntax

       USE MPI
       ! or the older form: INCLUDE 'mpif.h'
       MPI_FILE_WRITE_AT_ALL_END(FH, BUF, STATUS, IERROR)
            <type>    BUF(*)
            INTEGER   FH, STATUS(MPI_STATUS_SIZE), IERROR

C++ Syntax

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

       void MPI::File::Write_at_all_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_at_all_end is the ending part of a split collective routine that stores the
       number of elements actually written into the file associated with fh in status.  The  data
       is written into those parts of the file specified by the current view. All other fields of
       status are undefined.

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.
