noble (3) MPI_File_write_at_all_end.openmpi.3.gz

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

Fortran 2008 Syntax

       USE mpi_f08
       MPI_File_write_at_all_end(fh, buf, status, ierror)
            TYPE(MPI_File), INTENT(IN) :: fh
            TYPE(*), DIMENSION(..), INTENT(IN), ASYNCHRONOUS :: buf
            TYPE(MPI_Status) :: status
            INTEGER, OPTIONAL, INTENT(OUT) :: 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.
