MPI_File_read_at_all_begin - Begin a split collective read
       using explict offset


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_File_read_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_READ_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_read_at_all_begin begins a split collective read
       using an explict 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

       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.
