int* y)
Function Parameters
x |
a pointer filled with the last recorded x coordinate of the mouse |

Should this be an exception to the 'pointer rule'?

Code Examples
You can add your code example here
Remarks
The current button state is returned as a button bitmask, which can be tested using the SDL_BUTTON(X) macros *(where X is generally 1 for the left, 2 for middle, 3 for the right button)(parens is from SDL_GetMouseState because remark is otherwise the same)*, and x and y are set to the mouse deltas since the last call to SDL_GetRelativeMouseState() *or since event initialization. You can pass NULL for either x or y.*
