NAME

       MPI_File_read_at -  Read using explicit offset

SYNOPSIS

       int MPI_File_read_at(MPI_File fh, MPI_Offset offset, void *buf,
       int count, MPI_Datatype datatype, MPI_Status * status)

INPUT PARAMETERS

       fh     - file handle (handle)
       offset - file offset (nonnegative integer)
       count  - number of elements in buffer (nonnegative integer)
       datatype
              - datatype of each buffer element (handle)

OUTPUT PARAMETERS

       buf    - initial address of buffer (choice)
       status - status object (Status)

NOTES FOR FORTRAN

       All  MPI  routines  in  Fortran  (except  for MPI_WTIME and MPI_WTICK ) have an additional
       argument ierr at the end of the argument list.  ierr  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 (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.
