Expand description

Convert a string into SDL_GameControllerAxis enum.

This function is called internally to translate SDL_GameController mapping strings for the underlying joystick device into the consistent SDL_GameController mapping. You do not normally need to call this function unless you are parsing SDL_GameController mappings in your own code.

Note specially that “righttrigger” and “lefttrigger” map to SDL_CONTROLLER_AXIS_TRIGGERRIGHT and SDL_CONTROLLER_AXIS_TRIGGERLEFT, respectively.

\param str string representing a SDL_GameController axis \returns the SDL_GameControllerAxis enum corresponding to the input string, or SDL_CONTROLLER_AXIS_INVALID if no match was found.

\since This function is available since SDL 2.0.0.
