i did not worked much using pointer in lite-c. However the syntax of using
pointer in lite-c is different to ANSI-C.

There is no construct like *variable you would use to access a pointer. Regardless if a something is a variable or a pointer you access it always
with the variable name.

Wrong:
function update_paddle(var paddle_pos,var paddle_mode,var key)
*padde_pos = ponged_ball.pos_y - 42

Correct
function update_paddle(var* paddle_pos,var* paddle_mode,var* key)
padde_pos = ponged_ball.pos_y - 42
