Functions

ASensorEventQueue_disableSensor int ASensorEventQueue_disableSensor(ASensorEventQueue* queue, const(ASensor)* sensor): Disable the selected sensor.
ASensorEventQueue_enableSensor int ASensorEventQueue_enableSensor(ASensorEventQueue* queue, const(ASensor)* sensor): Enable the selected sensor at default sampling rate.
ASensorEventQueue_getEvents ssize_t ASensorEventQueue_getEvents(ASensorEventQueue* queue, ASensorEvent* events, size_t count): Retrieve pending events in sensor event queue
ASensorEventQueue_hasEvents int ASensorEventQueue_hasEvents(ASensorEventQueue* queue): Determine if a sensor event queue has pending event to be processed.
ASensorEventQueue_registerSensor int ASensorEventQueue_registerSensor(ASensorEventQueue* queue, const(ASensor)* sensor, int samplingPeriodUs, long maxBatchReportLatencyUs): Enable the selected sensor with sampling and report parameters
ASensorEventQueue_requestAdditionalInfoEvents int ASensorEventQueue_requestAdditionalInfoEvents(ASensorEventQueue* queue, bool enable): Request that {@link ASENSOR_TYPE_ADDITIONAL_INFO} events to be delivered on the given {@link ASensorEventQueue}.
ASensorEventQueue_setEventRate int ASensorEventQueue_setEventRate(ASensorEventQueue* queue, const(ASensor)* sensor, int usec): Sets the delivery rate of events in microseconds for the given sensor.
ASensorManager_configureDirectReport int ASensorManager_configureDirectReport(ASensorManager* manager, const(ASensor)* sensor, int channelId, int rate): Configure direct report on channel
ASensorManager_createEventQueue ASensorEventQueue* ASensorManager_createEventQueue(ASensorManager* manager, ALooper* looper, int ident, ALooper_callbackFunc callback, void* data): Creates a new sensor event queue and associate it with a looper.
ASensorManager_createHardwareBufferDirectChannel int ASensorManager_createHardwareBufferDirectChannel(ASensorManager* manager, const(AHardwareBuffer)* buffer, size_t size): Create direct channel based on AHardwareBuffer
ASensorManager_createSharedMemoryDirectChannel int ASensorManager_createSharedMemoryDirectChannel(ASensorManager* manager, int fd, size_t size): Create direct channel based on shared memory
ASensorManager_destroyDirectChannel void ASensorManager_destroyDirectChannel(ASensorManager* manager, int channelId): Destroy a direct channel
ASensorManager_destroyEventQueue int ASensorManager_destroyEventQueue(ASensorManager* manager, ASensorEventQueue* queue): Destroys the event queue and free all resources associated to it.
ASensorManager_getDefaultSensor const(ASensor)* ASensorManager_getDefaultSensor(ASensorManager* manager, int type): Returns the default sensor for the given type, or NULL if no sensor of that type exists.
ASensorManager_getDefaultSensorEx const(ASensor)* ASensorManager_getDefaultSensorEx(ASensorManager* manager, int type, bool wakeUp): Returns the default sensor with the given type and wakeUp properties or NULL if no sensor of this type and wakeUp properties exists.
ASensorManager_getInstance ASensorManager* ASensorManager_getInstance(): Get a reference to the sensor manager. ASensorManager is a singleton per package as different packages may have access to different sensors.
ASensorManager_getInstanceForPackage ASensorManager* ASensorManager_getInstanceForPackage(const(char)* packageName): Get a reference to the sensor manager. ASensorManager is a singleton per package as different packages may have access to different sensors.
ASensorManager_getSensorList int ASensorManager_getSensorList(ASensorManager* manager, ASensorList* list): Returns the list of available sensors.
ASensor_getFifoMaxEventCount int ASensor_getFifoMaxEventCount(const(ASensor)* sensor): Returns the maximum size of batches for this sensor. Batches will often be smaller, as the hardware fifo might be used for other sensors.
ASensor_getFifoReservedEventCount int ASensor_getFifoReservedEventCount(const(ASensor)* sensor): Returns the hardware batch fifo size reserved to this sensor.
ASensor_getHandle int ASensor_getHandle(const(ASensor)* sensor): Returns the sensor's handle.
ASensor_getHighestDirectReportRateLevel int ASensor_getHighestDirectReportRateLevel(const(ASensor)* sensor): Get the highest direct rate level that a sensor support.
ASensor_getMinDelay int ASensor_getMinDelay(const(ASensor)* sensor): Returns the minimum delay allowed between events in microseconds. A value of zero means that this sensor doesn't report events at a constant rate, but rather only when a new data is available.
ASensor_getName const(char)* ASensor_getName(const(ASensor)* sensor): Returns this sensor's name (non localized)
ASensor_getReportingMode int ASensor_getReportingMode(const(ASensor)* sensor): Returns the reporting mode for this sensor. One of AREPORTING_MODE_* constants.
ASensor_getResolution float ASensor_getResolution(const(ASensor)* sensor): Returns this sensors's resolution
ASensor_getStringType const(char)* ASensor_getStringType(const(ASensor)* sensor): Returns this sensor's string type.
ASensor_getType int ASensor_getType(const(ASensor)* sensor): Return this sensor's type
ASensor_getVendor const(char)* ASensor_getVendor(const(ASensor)* sensor): Returns this sensor's vendor's name (non localized)
ASensor_isDirectChannelTypeSupported bool ASensor_isDirectChannelTypeSupported(const(ASensor)* sensor, int channelType): Test if sensor supports a certain type of direct channel.
ASensor_isWakeUpSensor bool ASensor_isWakeUpSensor(const(ASensor)* sensor): Returns true if this is a wake up sensor, false otherwise.
