This function is called to notify us that a CPlayer's request has completed and what its status was.
|
|
|
1709 |
|
|
|
1710 |
It is important to note that:-
|
|
|
1711 |
1) RSoundSc driver PlayData requests are guaranteed to complete in order, oldest first
|
|
|
1712 |
2) If we are overloaded, it is possible for more than one request to complete before any CPlayer::RunL is ran. In
|
|
|
1713 |
this situation the CPlayer::RunL functions, and hence this callback, maybe invoked in non-oldest first order
|
|
|
1714 |
|
|
|
1715 |
but
|
|
|
1716 |
|
|
|
1717 |
a) It is impossible for callback for the second oldest CPlayer to occur before the driver request for the oldest has
|
|
|
1718 |
been complete (because of 1)
|
|
|
1719 |
b) We will always get exactly one callback for every complete request.
|
|
|
1720 |
|
|
|
1721 |
Therefore this callback notifies us of two subtly separate things:-
|
|
|
1722 |
|
|
|
1723 |
i) The oldest request has been completed (so we can reduce can increase the bytes played counter by its length
|
|
|
1724 |
ii) CPlayer aPlayerIndex is free for re-use
|
|
|
1725 |
|
|
|
1726 |
but we can not assume that aPlayerIndex is the oldest request, therefore we save the play request lengths outside of
|
|
|
1727 |
the CPlayer object.
