40 .Fn acl_dup "acl_t acl"
44 function returns a pointer to a copy of the ACL pointed to by the argument
47 This function may cause memory to be allocated. The caller should free any
48 releasable memory, when the new ACL is no longer required, by calling
54 Any existing ACL pointers that refer to the ACL referred to by
56 shall continue to refer to the ACL.
57 .Sh IMPLEMENTATION NOTES
59 support for POSIX.1e interfaces and features is still under
60 development at this time.
62 Upon successful completion, this function shall return a pointer to the
63 duplicate ACL. Otherwise, a value of
65 shall be returned, and
67 shall be set to indicate the error.
69 If any of the following conditions occur, the
71 function shall return a value of
75 to the corresponding value:
80 does not point to a valid ACL.
84 to be returned requires more memory than is allowed by the hardware or
85 system-imposed memory management constraints.
93 POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion
94 of the draft continues on the cross-platform POSIX.1e implementation
95 mailing list. To join this list, see the
97 POSIX.1e implementation
98 page for more information.
100 POSIX.1e support was introduced in
102 and development continues.

106 These features are not yet fully implemented. In particular, the shipped
107 version of UFS/FFS does not support storage of additional security labels,
108 and so is unable to (easily) provide support for most of these features.
