sdlGetRelativeMouseState function
Retrieve the relative state of the mouse.
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), 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
.
\param x a pointer filled with the last recorded x coordinate of the mouse \param y a pointer filled with the last recorded y coordinate of the mouse \returns a 32-bit button bitmask of the relative button state.
\since This function is available since SDL 2.0.0.
