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

           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.
