MPI_File_write_at_all_end(3OpenMPI)                                      MPI_File_write_at_all_end(3OpenMPI)



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, 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.
