sdlSetRelativeMouseTransform function mouse

bool sdlSetRelativeMouseTransform(Pointer<NativeFunction<SdlMouseMotionTransformCallback>> callback, Pointer<NativeType> userdata)

Set a user-defined function by which to transform relative mouse inputs.

This overrides the relative system scale and relative speed scale hints. Should be called prior to enabling relative mouse mode, fails otherwise.

\param callback a callback used to transform relative mouse motion, or NULL for default behavior. \param userdata a pointer that will be passed to callback. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.4.0.
