MPI_File_write_at_all_begin(3)

NAME
     MPI_File_write_at_all_begin - Begin a split collective write using
     explicit offset

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_File_write_at_all_begin( fh, offset, buf,
                                           count, datatype )
          MPI_File         fh;
          MPI_Offset       offset;
          void             *buf;
          int              count;
          MPI_Datatype     datatype;


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          <type> buf(*)
          INTEGER fh, count, datatype, ierror
          INTEGER(KIND=MPI_OFFSET_KIND) offset
          CALL MPI_FILE_WRITE_AT_ALL_BEGIN(fh, offset, buf,
          count, datatype, ierror)


STANDARDS
     This release implements the MPI 2.0 standard, as documented by the MPI
     Forum in the July 1997 release of MPI:  A Message Passing Interface
     Standard.

DESCRIPTION
     MPI_File_write_at_all_begin begins a split collective write using
     explicit offset.  This routine accepts the following parameters:

     fh             file handle (handle)

     offset         file offset (nonnegative integer)

     buf            initial address of buffer (choice)

     count          number of elements in buffer (nonnegative integer)

     datatype       datatype of each buffer element (handle)

Fortran Programs
     All MPI routines in Fortran (except for MPI_WTIME(3F) and MPI_WTICK(3F))
     have the additional argument ierror at the end of the argument list.
     ierror is an integer and has the same meaning as the return value of the
     routine in C.  In Fortran, MPI routines are subroutines, and are invoked
     with the CALL statement.

     All MPI objects (such as MPI_Datatype(3) and MPI_Comm(3)) are of type
     INTEGER in Fortran.
