###### (This is the legacy documentation for stable SDL2, the current stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current development version.) # SDL_GameControllerGetButtonFromString Convert a string into an [SDL_GameControllerButton](SDL_GameControllerButton) enum. ## Header File Defined in [SDL_gamecontroller.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_gamecontroller.h) ## Syntax ```c SDL_GameControllerButton SDL_GameControllerGetButtonFromString(const char *str); ``` ## Function Parameters | | | | ----------- | ------------------------------------------------------------------- | | **str** | string representing a [SDL_GameController](SDL_GameController) axis | ## Return Value Returns the [SDL_GameControllerButton](SDL_GameControllerButton) 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. ## Version This function is available since SDL 2.0.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction)
