set_piece_deadline()
--------------------
::
enum deadline_flags { alert_when_available = 1 };
void set_piece_deadline(int index, time_duration deadline, int flags = 0) const;
This function sets or resets the deadline associated with a specific piece
index (``index``). libtorrent will attempt to download this entire piece before
the deadline expires. This is not necessarily possible, but pieces with a more
recent deadline will always be prioritized over pieces with a deadline further
ahead in time. The deadline (and flags) of a piece can be changed by calling this
function again.
The ``flags`` parameter can be used to ask libtorrent to send an alert once the
piece has been downloaded, by passing ``alert_when_available``. When set, the
read_piece_alert_ alert will be delivered, with the piece data, when it's downloaded.
If the piece is already downloaded when this call is made, nothing happens, unless
the ``alert_when_available`` flag is set, in which case it will do the same thing
as calling read_piece_ for ``index``.
