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 | |
| typedef void * | haptic_device_h | 
| The haptic device handle. | |
| typedef void * | haptic_effect_h | 
| The haptic effect handle. | |

| int device_haptic_open | ( | int | device_index, | 
| haptic_device_h * | device_handle | ||
| ) | 
Opens a haptic-vibration device.
Internally, it makes a connection to the vibrator.

- 
  DEVICE_ERROR_NONE Successful DEVICE_ERROR_INVALID_PARAMETER Invalid parameter DEVICE_ERROR_PERMISSION_DENIED Permission denied DEVICE_ERROR_OPERATION_FAILED Operation failed DEVICE_ERROR_NOT_SUPPORTED Not supported device 
- See also:
- device_haptic_close()
| int device_haptic_stop | ( | haptic_device_h | device_handle, | 
| haptic_effect_h | effect_handle | ||
| ) | 
Stops all vibration effects which are being played.
This function can be used to stop all effects started by device_haptic_vibrate().

| int | duration, | ||
| int | feedback, | ||
| haptic_effect_h * | effect_handle | ||
| ) | 
Vibrates during the specified time with a constant intensity.
This function can be used to start monotonous vibration for the specified time.
