SDL_AddGamepadMapping

Add support for gamepads that SDL is unaware of or change the binding of an existing gamepad.

Header File

Defined in <SDL3/SDL_gamepad.h>

Syntax

int SDL_AddGamepadMapping(const char *mapping);

Function Parameters

const char * mapping the mapping string.

Return Value

(int) Returns 1 if a new mapping is added, 0 if an existing mapping is updated, -1 on error; call SDL_GetError() for more information.

Remarks

The mapping string has the format "GUID,name,mapping", where GUID is the string value from SDL_GetJoystickGUIDString(), name is the human readable string for the device and mappings are gamepad mappings to joystick ones. Under Windows there is a reserved GUID of "xinput" that covers all XInput devices. The mapping format for joystick is:

Buttons can be used as a gamepad axes and vice versa.

This string shows an example of a valid mapping for a gamepad:
