(This is the legacy documentation for stable SDL2, the current stable version; SDL3 is the current development version.)

SDL_GameControllerHasButton

Query whether a game controller has a given button.

Header File

Defined in SDL_gamecontroller.h, but apps should only #include "SDL.h"!

Syntax

SDL_bool SDL_GameControllerHasButton(SDL_GameController *gamecontroller,
                                     SDL_GameControllerButton button);

Function Parameters

gamecontroller	a game controller
button	a button enum value (an SDL_GameControllerButton value)

Return Value

Returns SDL_TRUE if the controller has this button, SDL_FALSE otherwise.

Remarks

This merely reports whether the controller's mapping defined this button, as that is all the information SDL has about the physical device.

Version

This function is available since SDL 2.0.14.
