In the C99 standard look at the definition of sequence > points (5.1.2.3) and the definition of volatile (6.7.3). 6.7.3 volatile bullet is non-normative. As pointed out in previous post: volatile accesses are observable. What 6.7.3 says is not a definition, but something which can be deduced from their status as observables. The key point which makes this waffle is the bit that says 'what constitutes an access is implementation defined'. -- John Skaller <skaller at users dot sf dot net> Felix, successor to C++: http://felix.sf.net
