Set relative mouse mode.


int SDL_SetRelativeMouseMode(SDL_bool enabled);

Function Parameters

enabled SDL_TRUE to enable relative mode, SDL_FALSE to disable.

Return Value

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.


While the mouse is in relative mode, the cursor is hidden, the mouse position is constrained to the window, and SDL will report continuous relative mouse motion even if the mouse is at the edge of the window.

This function will flush any pending mouse motion.


This function is available since SDL 3.0.0.
