Oh good point. What way would you prefer? I can add another parameter to the attribute, as in __attribute__((context(ctx,in,out,[read|write]))) (readwrite is implied), but that adds another parsing ambiguity. I have just sent you another patch (was offline for a few days) that probably won't apply without this, I'll fix this one and then do the other ones on top. johannes
