CBFSFILTER_EXTERNAL void* CBFSFILTER_CALL CBFSFilter_CBProcess_Get(void *lpObj, int propid, int arridx, int *lpcbVal, int64 *lpllVal);

Default Value



This property specifies how the class's system driver should behave if the specified Altitude is already in use when the StartFilter method is called.

If this property is enabled, the filter will fail to attach. If this property is disabled (default), the driver will attempt to use an adjacent altitude value to attach the filter.
