92 branded as NFSv4, will result in error.
93 .Sh IMPLEMENTATION NOTES
95 support for POSIX.1e interfaces and features is still under
96 development at this time.
100 If any of the following conditions occur, these functions shall return
103 to the corresponding value:
106 Search permission is denied for a component of the path prefix, or the
107 object exists and the process does not have appropriate access rights.
111 argument is not a valid file descriptor.
115 does not point to a valid ACL for this object, or the ACL type
118 is invalid for this object, or there is branding mismatch.
119 .It Bq Er ENAMETOOLONG
120 A component of a pathname exceeded 255 characters, or an
121 entire path name exceeded 1023 characters.
123 The named object does not exist, or the
125 argument points to an empty string.
127 Insufficient memory available to fulfill request.
129 The directory or file system that would contain the new ACL cannot be
130 extended, or the file system is out of file allocation resources.
132 The file system does not support ACL retrieval.
134 This function requires modification of a file system which is currently
141 .Xr acl_get_brand_np 3 ,
145 POSIX.1e is described in IEEE POSIX.1e draft 17.
147 of the draft continues on the cross-platform POSIX.1e implementation
149 To join this list, see the
151 POSIX.1e implementation
152 page for more information.
154 POSIX.1e support was introduced in
156 and development continues.
