This comment for set_config_option() leads me to think we should be returning -1 instead of 0 in many more places in set_config_with_handle(): * Return value: * +1: the value is valid and was successfully applied. * 0: the name or value is invalid (but see below). * -1: the value was not applied because of context, priority, or changeVal. But I haven't thought through it, either. At this point, maybe the comment is wrong... -- nathan
