int SDL_HapticNumEffects | ( | SDL_Haptic * | haptic | ) |
Returns the number of effects a haptic device can store.
On some platforms this isn't fully supported, and therefore is an approximation. Always check to see if your created effect was actually created and do not rely solely on SDL_HapticNumEffects().

SDL_Haptic* SDL_HapticOpen | ( | int | device_index | ) |
Opens a Haptic device for usage.
The index passed as an argument refers to the N'th Haptic device on this system.
When opening a haptic device, its gain will be set to maximum and autocenter will be disabled. To modify these values use SDL_HapticSetGain() and SDL_HapticSetAutocenter().

SDL_Haptic* SDL_HapticOpenFromJoystick | ( | SDL_Joystick * | joystick | ) |
Opens a Haptic device for usage from a Joystick device.
You must still close the haptic device seperately. It will not be closed with the joystick.
When opening from a joystick you should first close the haptic device before closing the joystick device. If not, on some implementations the haptic device will also get unallocated and you'll be unable to use force feedback on that device.

Pauses a haptic device.
Device must support the SDL_HAPTIC_PAUSE feature. Call SDL_HapticUnpause() to resume playback.
