I'm using MacFUSE to create a cool filesystem. I'd like to set the NSFileOwnerAccountID
and NSFileGroupOwnerAccountID
attributes for the files on it, but the underlying framework I use only gives me user names.
How can I get an account ID from an account name under Mac OS X using Cocoa or other built-in frameworks?
What you could do is get a list of all the CSIdentity
objects and build a "username to identity" map. Once you have the identity object, you can get a bunch of other information from it.
More info:
These are just UID and GID numbers. Try the getpwnam
(for user) and getgrnam
(for group) functions; each returns a structure that contains the ID number, among other things.
Alternatively, just use NSFileOwnerAccountName
and NSFileGroupOwnerAccountName
instead of the …AccountID
versions.
