Functions
| CollectionsListAllocateBufferAndSerialize This routine allocates a buffer and then serializes a sensor collection list to it. |
| CollectionsListCopyAndMarshall This routine copies and marshalls a collection list from source to target. |
| CollectionsListDeserializeFromBuffer This routine deserializes a collection list from the input buffer. |
| CollectionsListGetFillableCount Returns the number of elements a SENSOR_COLLECTION_LIST buffer of a certain size can possibly hold. |
| CollectionsListGetMarshalledSize Returns the size needed to accommodate serializing and marshaling a collection list, including embedded memory. |
| CollectionsListGetMarshalledSizeWithoutSerialization Returns the size of the entire collection list, including size of memories blocks that are pointed by embedded pointers. |
| CollectionsListGetSerializedSize This routine returns the larger of the two sizes to provide for sufficient buffer sizes to accommodate passing the collection list across processes that can have different bit-ness values. |
| CollectionsListMarshall This routine is similar to CollectionsListCopyAndMarshall, except that it marshalls a collection list in-place. |
| CollectionsListSerializeToBuffer This routine serializes a collection list to the caller-allocated buffer. |
| CollectionsListSortSubscribedActivitiesByConfidence This routine rearranges activity data collection under certain conditions. |
| CollectionsListUpdateMarshalledPointer This routine update embedded pointers. |
| EvaluateActivityThresholds This routine determines whether the new incoming activity data meets the threshold. |
| GetPerformanceTime This routine calculates system time in milliseconds. |
| InitPropVariantFromCLSIDArray This routine initializes a PROPVARIANT from a given array of GUIDs. |
| InitPropVariantFromFloat This routine initializes a PROPVARIANT with the given float. |
| IsCollectionListSame This routine compares two collection lists to see if they are the same. |
| IsGUIDPresentInList This routine looks for a GUID in a list of GUIDs. |
| IsKeyPresentInCollectionList This routine determine if a key is present in a collection list. |
| IsKeyPresentInPropertyList This routine determine if a key is present in a property list. |
| IsSensorSubscribed For internal use only. |
| MILLISECONDS_FROM_100NANOSECONDS This macro converts time, provided as 100 nanosecond units, to milliseconds. |
| MILLISECONDS_TO_100NANOSECONDS This macro converts time, in milliseconds, to 100 nanosecond units. |
| PropertiesListCopy This routine copies a properties list from source to target. |
| PropertiesListGetFillableCount Returns the number of elements a properties list buffer of a certain size can possibly hold. |
| PropKeyFindKeyGetBool This routine gets a BOOL value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetDouble This routine gets a double precision floating point value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetFileTime This routine gets a FILETIME value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetFloat This routine gets a single precision floating point value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetGuid This routine gets a GUID value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetInt32 This routine gets an INT32 value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetInt64 This routine gets an INT64 value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetNthInt64 This routine gets the nth INT64 value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetNthUlong This routine gets the nth ULONG value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetNthUshort This routine gets the nth USHORT value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetPropVariant This routine finds the PROPVARIANT from a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetUlong This routine gets a ULONG value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeyGetUshort This routine gets a USHORT value from a PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropKeyFindKeySetPropVariant This routine finds and sets the PROPVARIANT within a collection list based on the PROPERTYKEY. |
| PropVariantGetInformation This routine gets offset, size, location pointer and DEVPROPTYPE, of a PROPVARIANT. |
| SensorCollectionGetAt This routine returns the PROPERTYKEY and PROPVARIANT associated with the nth element in the provided sensor collection list. |
| SerializationBufferAllocate Exported memory allocation function for allocating a serialized buffer. |
| SerializationBufferFree Exported memory allocation function for freeing a serialization buffer. |
