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.
