Convert a string into an SDL_GameControllerButton enum.
const char *str);SDL_GameControllerButton SDL_GameControllerGetButtonFromString(
|str||string representing a SDL_GameController axis|
Returns the SDL_GameControllerButton enum corresponding to the input string, or
SDL_CONTROLLER_AXIS_INVALID if no match was found.
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.
This function is available since SDL 2.0.0.
