###### (This is the legacy documentation for SDL2, the previous stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current stable version.) # SDL_GameControllerGetAxisFromString Convert a string into [SDL_GameControllerAxis](SDL_GameControllerAxis) enum. ## Header File Defined in [SDL_gamecontroller.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_gamecontroller.h) ## Syntax ```c SDL_GameControllerAxis SDL_GameControllerGetAxisFromString(const char *str); ``` ## Function Parameters | | | | | ------------ | ------- | -------------------------------------------------------------------- | | const char * | **str** | string representing a [SDL_GameController](SDL_GameController) axis. | ## Return Value ([SDL_GameControllerAxis](SDL_GameControllerAxis)) Returns the [SDL_GameControllerAxis](SDL_GameControllerAxis) enum corresponding to the input string, or [`SDL_CONTROLLER_AXIS_INVALID`](SDL_CONTROLLER_AXIS_INVALID) if no match was found. ## Remarks This function is called internally to translate [SDL_GameController](SDL_GameController) mapping strings for the underlying joystick device into the consistent [SDL_GameController](SDL_GameController) mapping. You do not normally need to call this function unless you are parsing [SDL_GameController](SDL_GameController) mappings in your own code. Note specially that "righttrigger" and "lefttrigger" map to [`SDL_CONTROLLER_AXIS_TRIGGERRIGHT`](SDL_CONTROLLER_AXIS_TRIGGERRIGHT) and [`SDL_CONTROLLER_AXIS_TRIGGERLEFT`](SDL_CONTROLLER_AXIS_TRIGGERLEFT), respectively. ## Version This function is available since SDL 2.0.0. ## See Also - [SDL_GameControllerGetStringForAxis](SDL_GameControllerGetStringForAxis) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryGameController](CategoryGameController)
