NAME

       MPI_File_iread_at_all -  Nonblocking collective read using explicit offset

SYNOPSIS

       int MPI_File_iread_at_all(MPI_File fh, MPI_Offset offset, void *buf,
       int count, MPI_Datatype datatype, MPI_Request * request)

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)
       request
              - request object (handle)

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.
