:ref:`MPI_File_read_all_end` |mdash| Reads a file starting at the locations
specified by individual file pointers; ending part of a split collective
routine (blocking).

INPUT/OUTPUT PARAMETER
----------------------
* ``fh``: File handle (handle).

OUTPUT PARAMETERS
-----------------
* ``buf``: Initial address of buffer (choice).
* ``status``: Status object (status).
* ``ierror``: Fortran only: Error status (integer).

DESCRIPTION
-----------

:ref:`MPI_File_read_all_end` is the ending part of a split collective operation
that stores the number of elements actually read from the file
associated with *fh* (at the current individual file pointer position
maintained by the system) into the user's buffer *buf* in *status.* The
data is taken out of 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.
