SDL_JoystickOpen

Open a joystick for use.

Syntax

SDL_Joystick* SDL_JoystickOpen(int device_index);

Function Parameters

device_index

the index of the joystick to query

Return Value

Returns a joystick identifier or NULL if an error occurred; call SDL_GetError() for more information.

Remarks

The device_index argument refers to the N'th joystick presently recognized by SDL on the system. It is NOT the same as the instance ID used to identify the joystick in future events. See SDL_JoystickInstanceID() for more details about instance IDs.

The joystick subsystem must be initialized before a joystick can be opened for use.

Version

This function is available since SDL 2.0.0.
