The 52.Fn acl_extended_file_nofollow_np 53function works the same way, except it does not follow symlinks. The 54.Fn acl_extended_link_np 55function is a synonim to 56.Fn acl_extended_file_nofollow_np 57named in FreeBSD style. 58An ACL is considered to be extended access one if it contains entries other 59than the three required entries of tag types ACL_USER_OBJ, ACL_GROUP_OBJ and 60ACL_OTHER. 61.Sh RETURN VALUES 62Upon successful completion, this function returns 0 if the file object does not 63contain extended access ACLs and 1 in the other case. 64Otherwise, the value -1 is returned, and 65.Va errno 66indicates the error. 67.Sh ERRORS 68If any of the following conditions occur, the 69.Fn acl_extended_file_np 70function shall return a value of 71.Va -1 72and set 73.Va errno 74to the corresponding value: 75.Bl -tag -width Er 76.It Bq Er EACCES 77Search permission is denied for a component of the path prefix. 78.El 79.Sh SEE ALSO 80.Xr extattr_get_file 2 , 81.Xr posix1e 3 82.Sh STANDARDS 83POSIX.1e is described in IEEE POSIX.1e draft 17. 84Discussion 85of the draft continues on the cross-platform POSIX.1e implementation 86mailing list. 87To join this list, see the 88.Fx 89POSIX.1e implementation 90page for more information. 91.Sh HISTORY 92POSIX.1e support was introduced in 93.Fx 4.0 , 94and development continues. 95.Sh AUTHORS 96.An Gleb Popov 97
