66 .Sh IMPLEMENTATION NOTES
68 support for POSIX.1e interfaces and features is still under
69 development at this time.
73 If any of the following conditions occur, these functions shall return
76 to the corresponding value:
79 Search permission is denied for a component of the path prefix, or the
80 object exists and the process does not have appropriate access rights.
84 argument is not a valid file descriptor.
88 does not point to a valid ACL for this object, or the ACL type
91 is invalid for this object, or both.
92 .It Bq Er ENAMETOOLONG
93 A component of a pathname exceeded 255 characters, or an
94 entire path name exceeded 1023 characters.
96 The named object does not exist, or the
98 argument points to an empty string.
100 Insufficient memory available to fulfill request.
102 The directory or file system that would contain the new ACL cannot be
103 extended, or the file system is out of file allocation resources.
105 The file system does not support ACL retrieval.
107 This function requires modification of a file system which is currently
117 POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion
118 of the draft continues on the cross-platform POSIX.1e implementation
119 mailing list. To join this list, see the
121 POSIX.1e implementation
122 page for more information.
124 POSIX.1e support was introduced in
126 and development continues.

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