Tizen Native API
|
The Haptic API provides functions to control a vibrator.
Required Header
#include <device/haptic.h>
Overview
The Haptic API provides the way to control vibration functionality of a device. It allows the management of the device's vibrator parameters, such as the vibration count and level.
Functions | |
| int | device_haptic_get_count (int *device_number) |
| Gets the number of vibrators. | |
| int | device_haptic_open (int device_index, haptic_device_h *device_handle) |
| Opens a haptic-vibration device. | |
| int | device_haptic_close (haptic_device_h device_handle) |
| Closes a haptic-vibration device. | |
| int | device_haptic_vibrate (haptic_device_h device_handle, int duration, int feedback, haptic_effect_h *effect_handle) |
| Vibrates during the specified time with a constant intensity. | |
| int | device_haptic_stop (haptic_device_h device_handle, haptic_effect_h effect_handle) |
| Stops all vibration effects which are being played. | |
Typedefs | |
