Remarks
This property returns a structure of type KSPIN_CINSTANCES:
typedef struct {
ULONG PossibleCount;
ULONG CurrentCount;
} KSPIN_CINSTANCES;
The following is a description of each member of the KSPIN_CINSTANCES structure.
PossibleCount
Specifies the maximum number of pins the pin factory can instantiate on the filter, or KSINTANCE_INDETERMINATE if there is no maximum.
CurrentCount
Specifies the current number of pins the pin factory has instantiated on the filter.
This property specifies the per-filter maximum for a given pin factory. Use the KSPROPERTY_PIN_GLOBALCINSTANCES property to specify the overall maximum for a given pin factory.
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.
