KsGateRemoveOnInputFromOr function (ks.h)
The KsGateRemoveOnInputFromOr function removes an existing input that is in the ON state from an OR gate.
Syntax
void KsGateRemoveOnInputFromOr(
[in] PKSGATE OrGate
);
Parameters
[in] OrGate
A pointer to a KSGATE structure representing the OR gate from which to remove an ON input.
Return value
None
Remarks
Removing the last ON input from a given OR gate results in the gate closing and the transition being propagated to any gates connected to OrGate. For more information, see Flow Control Gates in AVStream.
KsGateRemoveOnInputFromOr should only be used on gates that were specifically created as AND gates; AVStream does not verify that the given gate is an AND gate.
This call is an inline function call to KsGateTurnInputOff. If conceptually removing an existing input to a gate, a minidriver should call KsGateRemoveOnInputFromOr rather than KsGateTurnInputOff.
