Open a haptic device for use.


SDL_Haptic* SDL_HapticOpen(int device_index);

Function Parameters

device_index index of the device to open

Return Value

Returns the device identifier or NULL on failure; call SDL_GetError() for more information.


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().
