Function sdl2_sys::SDL_SetWindowMouseRect

pub unsafe extern "C" fn SDL_SetWindowMouseRect(
    window: *mut SDL_Window,
    rect: *const SDL_Rect
) -> c_int

Confines the cursor to the specified area of a window.

Note that this does NOT grab the cursor, it only defines the area a cursor is restricted to when the window has mouse focus.

\param window The window that will be associated with the barrier. \param rect A rectangle area in window-relative coordinates. If NULL the barrier for the specified window will be destroyed. \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.18.
