29.Sh NAME
30.Nm acl_extended_file_np ,
31.Nm acl_extended_file_nofollow_np ,
32.Nm acl_extended_link_np
33.Nd checks if the file has extended ACLs set
34.Sh LIBRARY
35.Lb libc
36.Sh SYNOPSIS
37.In sys/types.h
38.In sys/acl.h
39.Ft int
40.Fn acl_extended_file_np "const char* path_p"
41.Ft int
42.Fn acl_extended_file_nofollow_np "const char* path_p"
43.Ft int
44.Fn acl_extended_link_np "const char* path_p"
45.Sh DESCRIPTION
46The
47.Fn acl_extended_file_np
48function is a non-portable call that checks if the file or directory referred to
49by the argument
50.Va path_p
51contains extended access ACLs. 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.
