The KSPROPERTY_PIN_CONSTRAINEDDATARANGES property specifies the list of data ranges currently supported by pins instantiated on the pin factory.
KSP_PIN. The PinId member specifies the pin factory.
A KSMULTIPLE_ITEM structure, followed by a sequence of 64-bit aligned KSDATARANGE structures.
KSPROPERTY_PIN_CONSTRAINEDDATARANGES is read-only.
A KS filter uses this property to report the data ranges currently supported by pins instantiated on this pin factory, based on any constraints imposed by the current internal state of the KS filter. Use the KSPROPERTY_PIN_DATARANGES property to report the complete list of all data ranges supported by the KS filter, regardless of dynamic constraints.
Stream minidrivers do not need to handle this property directly; the stream class driver handles this property using stream request blocks to query for more information.
