We then parse out the dn. How can I accomplish the same using the Open Directory API? Why not use the openldap tools/api? Are you wanting to deal with more cases than just a pure Open Directory setup? You could always interrogate the /Config branch to work out the search base and where users are kept?

All of the following consistently return ENOENT: acl_delete_file_np(), acl_delete_link_np(), and acl_delete_fd_np(), though the path or file descriptor is valid. When I walk into the library routine's assembly code, it looks like the call is stubbed out -- pop the stack and then return to the caller. Does anyone know the status of the acl_delete routines under OS X 10.4.7? If indeed they aren't functional, is the best work-around to delete acl entries one-by-one? Deleting entries one by one gives you an ACL with zero entries, which is not the same as no ACL at all; in particular, Windows systems will interpret this as "deny all", vs. "allow all" implied by having no ACL. You can remove the ACL on a file with setattrlist(2), by specifying an ACL with an entrycount of KAUTH_FILESEC_NOACL. This is handled by this slightly dodgy fragment of code in xnu/bsd/vfs/vfs_attrlist.c: nace = rfsec->fsec_acl.acl_entrycount; if (nace == KAUTH_FILESEC_NOACL) { /* deleting ACL */ VATTR_SET(&va, va_acl, NULL); } else { = Mike _______________________________________________ Do not post admin requests to the list.

In particular, setattrlist takes the kauth_filesec_t structure which is not really meant to be exposed. This email sent to site_archiver(a)lists.apple.com

suggestions to develop a PCI driver

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… This email sent to site_archiver(a)lists.apple.com I have linux version of the PCI card that receives ASI input. I have attached the linux driver source code for the card. I would like to know what sample driver files are the best ones to look at so that I can get started with porting that to Mac OS X. Can anyone please suggest/send some example PCI driver that has close resemblance with what I am trying to do? I have read writing PCI drivers and IOKit guidelines documents on Apple's websites. I have also skimmed through Godfrey's 'PCI driver tutorial' series sent out through the list. I would really appreciate whatever inputs/pointers you can give. I have already done the skeleton driver. However, I find some difficulties in implementing the interrupt handling as well as DMA operation to be specific. asidriver.rar
