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 libc
38.Sh SYNOPSIS
39.In sys/types.h
40.In 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
64.Rv -std
65.Sh ERRORS
66If any of the following conditions occur, these functions shall return -1
67and set
68.Va errno
69to the corresponding value:
70.Bl -tag -width Er
71.It Bq Er EACCES
72Search permission is denied for a component of the path prefix, or the
73object exists and the process does not have appropriate access rights.
74.It Bq Er EBADF
75The
76.Va fd
77argument is not a valid file descriptor.
78.It Bq Er EINVAL
79The ACL type passed is invalid for this file object.
80.It Bq Er ENAMETOOLONG
81A component of a pathname exceeded 255 characters, or an
82entire path name exceeded 1023 characters.
83.It Bq Er ENOENT
84The named object does not exist, or the
85.Va path_p
86argument points to an empty string.
87.It Bq Er ENOMEM
88Insufficient memory available to fulfill request.
89.It Bq Er ENOTDIR
90A component of the path prefix is not a directory.
91.Pp
92Argument
93.Va path_p
94must be a directory, and is not.
95.It Bq Er EOPNOTSUPP
96The file system does not support ACL deletion.
97.It Bq Er EPERM
98The process does not have appropriate privilege to perform the operation
99to delete an ACL.
100.It Bq Er EROFS
101The file system is read-only.

108.Sh STANDARDS
109POSIX.1e is described in IEEE POSIX.1e draft 17.  Discussion
110of the draft continues on the cross-platform POSIX.1e implementation
111mailing list.  To join this list, see the
112.Fx
113POSIX.1e implementation
114page for more information.
115.Sh HISTORY
116POSIX.1e support was introduced in
117.Fx 4.0 ,
118and development continues.
