Hi,

yup, that idea works perfectly.

------------------------------------------------------------ 
--note these are decalared outside of the function, so don't need to keep recreating them 
atom mousePtr = allocate_struct(SDL_Point) 
atom Amx, Amy 
--this way - create and SDL_Point structure, and pass those addresses to the SDL_GetMouseState function 
Amx = mousePtr 
Amy = mousePtr + sizeof(C_UINT32) 
function scanMouse_b(atom e) 
------------------------------------------------------------ 
sequence scanned = repeat(0, sizeof(SDL_Event)) 
integer event_type = peek_type(e, C_UINT32) 
integer mx, my, mouseState 
 
mouseState = SDL_GetMouseState(Amx,Amy) 
 
mx = peek4u(Amx) 
my = peek4u(Amy) 
 
printf(1, "%d     , %d     \n", {mx,my}) 
 
return eMouse 
end function 
 

And also note the use of ffi - I understand it so much better now, and much easier than before. You're not allowed to change it Greg.

Cheers

Chris
