I am trying to allocate a wired page to transfer data. Typically you don't want to do this; instead you would transfer directly to your client's memory. If you're reading documents, I encourage you to read the one that explains two-machine debugging. You're not going to get very far developing a device driver without some capacity for debugging your mistakes, and this mailing list is no substitute for the proper tools. I would also encourage you to explore the large amount of I/O Kit device driver source available on the web, and look for examples of the sort of things that your driver needs to do. If you're not willing or able to share your source code with us, there is little or no help that we can offer in return when confronted with questions like the one you've asked above.

If you look at the 10.4.6 sources via: <http://darwinsource.opendarwin.org/10.4.6.ppc/Libc-391.2.5/posix1e/acl_file .c> you'll see that they are indeed mostly stubs.

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Dave, Thanks. I do exactly this programatically. But, I am looking up users. For example, dscl localhost -read /Search/Users/rick distinguishedName This assumes that there is a "distinguishedName" attribute in the object. But, if you use something like openldap, there is no such attribute. So, when using dscl localhost -read /Search/Users/rick to display the entire object, I do not see the distinguishedName attribute. But, when I use openldap's search client, I execute ldapsearch -LLL -x 'uidNumber=1000' dn I get dn: uid=rick,ou=People,dc=foobar,dc=biz So, I read this as the distinguished name for the object whos attribute uidNumber is 1000 is uid=rick,ou=People,dc=foobar,dc=biz That is what I am after in osx :-) --joubert I've written code to do the equivalent of dscl localhost -read /Search/Computers/`hostname -s` distinguishedName programmatically, but if you can shell out to dscl to do it your life is much simpler.

That ought to fail, because "distinguishedName" is only present in the LDAP/X.500 schema as an attribute supertype. DNs of entries in LDAP/X.500 are *not* held in attributes of the entries.
