SCSL_Draw_Rect has no declared return type, and no return value, so I
guess it defaults to 0 as an int. Assuming that lua_pushcfunction with
a NULL parameter doesn't throw an error, I'd expect lua_call to throw.
Also the lua_call is passed parameter 5, while only 4 lua_pushinteger
are not commented out, so what is pushed by lua_pushfunction is not
even called. I don't know what is called though.
The pasted code has so many such problems I seriously doubts the
reported symptoms (the printf works but not the draw) are really what
