Aha - so Hans want open() to work on directories only when app does
open("/etc", O_OPEN_DIRECTORY_AS_FILE)
? That will not break anything, but I doubt it is better than
open("/etc#opendirasfile", O_RDONLY)
which has advantage of easily going through network, advantage of user being able to explicitly ask for this even for old apps (think cat /etc - how do you convince cat to use O_OPEN_DIRECTORY_AS_FILE? You add option? And why adding option when cat /etc#opendirasfile works nicer?)
Pavel PS: The latter complete with syntax has one advantage: it is already implemented ;-).
PPS: Hans, please try not to change subject lines in every posting. The whole thread is much easier to kill that way :-). -- I'm really pavel@ucw.cz. Look at http://195.113.31.123/~pavel. Pavel Hi! I'm a .signature virus! Copy me into your ~/.signature, please!
