Excellent! Erwan should really look how we could use that to build a back end for Lumiere or Klotz. Alex :) Fernando :) It will be really fun.

You are great enabler. COntinue. Of course we want to do too much because this is exciting. So let us check and focus on the fundamentals. April will be a crazy month :) Stef

The spAlien is a pointer to the incoming C callback stack frame, i.e. a pointer to the callback's parameters. So spAlien unsignedLongAt: 5 gets the four-byte pointer for the void * parameter, wraps it up in a convenient pointer Alien (so the callback block can e.g. indirect through it to get at the data the pointer is pointing to), and passes it as the second argument of the callback block. But the two Alien newC: 4's are entirely bogus, passing effectively uninitialized data for the first and third parameters of the callback block. They're just empty Aliens, when in fact you want to pass two longs to the block for the first and third parameters. So to pass values in you need something like: longVoidStarLongRetInt: callbackContext sp: spAlien <signature: 'int (*) (long, void *, long)' abi: 'IA32'> ^callbackContext wordResult: (block value: (spAlien signedLongAt: 1) value: (Alien forPointer: (spAlien unsignedLongAt: 5)) value: (spAlien signedLongAt: 9) ) You might also need to consider passing the result of the block back out. If you only want to use it to answer integers then the above is fine. But take a look at the intcharstarRetint:sp: signature: intcharstarRetint: callbackContext sp: spAlien <signature: 'int (*)(int, char *)' abi: 'IA32'> ^callbackContext wordResult: ((block value: (spAlien signedLongAt: 1) ~= 0 value: (Alien forPointer: (spAlien unsignedLongAt: 5)) strcpyUTF8) ifNil: [0] ifNotNil: [:result| result isInteger ifTrue: [result] ifFalse: [result == true ifTrue: [1] ifFalse: [0]]]) Analogously it passes a signed integer as the first argument and a UTF8 string derived from the second char * parameter. (The method should probably be called intcharstarasUTF8Retint:sp: or some such; forgive me, we're getting there). But on return it takes the result of the callback block and passes it to the ifNil:ifNotNil: which - maps a nil result form the block to 0 (ifNil: [0]) - maps integers to integers (which will only deal correctly with integers in the 32-bit range), and - maps true to 1, mapping all other results to 0. Does what's going on now make more sense?
