56 is a POSIX.1e call that deletes the default ACL from a file (normally a
57 directory) by name; the other two calls are non-portable extensions that
58 allow deleting of arbitrary ACL types from a file/directory by either path
59 name, or by file descriptor.
60 .Sh IMPLEMENTATION NOTES
62 support for POSIX.1e interfaces and features is still under
63 development at this time.
67 If any of the following conditions occur, these functions shall return -1
70 to the corresponding value:
73 Search permission is denied for a component of the path prefix, or the
74 object exists and the process does not have appropriate access rights.
78 argument is not a valid file descriptor.
80 The ACL type passed is invalid for this file object.
81 .It Bq Er ENAMETOOLONG
82 A component of a pathname exceeded 255 characters, or an
83 entire path name exceeded 1023 characters.
85 The named object does not exist, or the
87 argument points to an empty string.
89 Insufficient memory available to fulfill request.
91 A component of the path prefix is not a directory.
95 must be a directory, and is not.
97 The file system does not support ACL deletion.
99 The process does not have appropriate privilege to perform the operation
102 The file system is read-only.
110 POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion
111 of the draft continues on the cross-platform POSIX.1e implementation
112 mailing list. To join this list, see the
114 POSIX.1e implementation
115 page for more information.
117 POSIX.1e support was introduced in
119 and development continues.

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