Usage Summary Table

|---|---|---|---|---|
| Yes | Yes | Pin | KSPROPERTY | KSPRIORITY |
Remarks
This property returns a structure of type KSPRIORITY that contains a priority class and subclass.
One priority is greater than another if the PriorityClass member is greater, or if the PriorityClass members are identical and the PrioritySubClass member is greater.
The following predefined values of PriorityClass are available: KSPRIORITY_LOW, KSPRIORITY_NORMAL, KSPRIORITY_HIGH, and KSPRIORITY_EXCLUSIVE. Priority defaults to KSPRIORITY_NORMAL. KSPRIORITY_EXCLUSIVE indicates the connection has exclusive access to resources used by a pin.
The priority values have global significance: a client can use the reported values to set priorities between two different pins on two unrelated kernel streaming filters.
KSPROPERTY_CONNECTION_PRIORITY is optional. Clients treat pins that do not support it as having priority KSPRIORITY_NORMAL.
