41 .Fn acl_dup "acl_t acl"
45 function returns a pointer to a copy of the ACL pointed to by the argument
48 This function may cause memory to be allocated. The caller should free any
49 releasable memory, when the new ACL is no longer required, by calling
55 Any existing ACL pointers that refer to the ACL referred to by
57 shall continue to refer to the ACL.
58 .Sh IMPLEMENTATION NOTES
60 support for POSIX.1e interfaces and features is still under
61 development at this time.
63 Upon successful completion, this function shall return a pointer to the
64 duplicate ACL. Otherwise, a value of
66 shall be returned, and
68 shall be set to indicate the error.
70 If any of the following conditions occur, the
72 function shall return a value of
76 to the corresponding value:
81 does not point to a valid ACL.
85 to be returned requires more memory than is allowed by the hardware or
86 system-imposed memory management constraints.
94 POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion
95 of the draft continues on the cross-platform POSIX.1e implementation
96 mailing list. To join this list, see the
98 POSIX.1e implementation
99 page for more information.
101 POSIX.1e support was introduced in
103 and development continues.

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