32.Nm acl_delete_def_file ,
33.Nm acl_delete_fd_np ,
34.Nm acl_delete_file_np
35.Nd delete an ACL from a file
36.Sh LIBRARY
37.Lb libposix1e
38.Sh SYNOPSIS
39.Fd #include <sys/types.h>
40.Fd #include <sys/acl.h>
41.Ft int
42.Fn acl_delete_def_file "const char *path_p"
43.Ft int
44.Fn acl_delete_file_np "const char *path_p" "acl_type_t type"
45.Ft int
46.Fn acl_delete_fd_np "int filedes" "acl_type_t type"
47.Sh DESCRIPTION
48The
49.Fn acl_delete_def_file ,
50.Fn acl_delete_file_np ,
51and
52.Fn acl_delete_fd_np
53each allow the deletion of an ACL from a file.
54.Fn acl_delete_def_file
55is a POSIX.1e call that deletes the default ACL from a file (normally a
56directory) by name; the other two calls are non-portable extensions that
57allow deleting of arbitrary ACL types from a file/directory by either path
58name, or by file descriptor.
59.Sh IMPLEMENTATION NOTES
60.Fx Ns 's
61support for POSIX.1e interfaces and features is still under
62development at this time.
63.Sh RETURN VALUES
64In the event of success, 0 is returned.  In the event of failure, -1 is
65returned, and
66.Va errno
67is set to indicate the error.
68.Sh ERRORS
69If any of the following conditions occur, these functions shall return -1
70and set
71.Va errno
72to the corresponding value:
73.Bl -tag -width Er
74.It Bq Er EACCES
75Search permission is denied for a component of the path prefix, or the
76object exists and the process does not have appropriate access rights.
77.It Bq Er EBADF
78The
79.Va fd
80argument is not a valid file descriptor.
81.It Bq Er EINVAL
82The ACL type passed is invalid for this file object.
83.It Bq Er ENAMETOOLONG
84A component of a pathname exceeded 255 characters, or an
85entire path name exceeded 1023 characters.
86.It Bq Er ENOENT
87The named object does not exist, or the
88.Va path_p
89argument points to an empty string.
90.It Bq Er ENOMEM
91Insufficient memory available to fulfill request.
92.It Bq Er ENOTDIR
93A component of the path prefix is not a directory.
94
95Argument
96.Va path_p
97must be a directory, and is not.
98.It Bq Er EOPNOTSUPP
99The file system does not support ACL deletion.
100.It Bq Er EPERM
101The process does not have appropriate privilege to perform the operation
102to delete an ACL.
103.It Bq Er EROFS
104The file system is read-only.

111.Sh STANDARDS
112POSIX.1e is described in IEEE POSIX.1e draft 17.  Discussion
113of the draft continues on the cross-platform POSIX.1e implementation
114mailing list.  To join this list, see the
115.Fx
116POSIX.1e implementation
117page for more information.
118.Sh HISTORY
119POSIX.1e support was introduced in
120.Fx 4.0 ,
121and development continues.
