41.In sys/types.h
42.In sys/acl.h
43.Ft int
44.Fn acl_delete_def_file "const char *path_p"
45.Ft int

53.Sh DESCRIPTION
54The
55.Fn acl_delete_def_file ,
56.Fn acl_delete_def_link_np ,
57.Fn acl_delete_fd_np ,
58.Fn acl_delete_file_np ,
59and
60.Fn acl_delete_link_np
61each allow the deletion of an ACL from a file.
62The
63.Fn acl_delete_def_file
64function
65is a POSIX.1e call that deletes the default ACL from a file (normally a
66directory) by name; the remainder of the calls are non-portable extensions
67that permit the deletion of arbitrary ACL types from a file/directory
68either by path name or file descriptor.
69The
70.Fn _file
71variations follow a symlink if it occurs in the last segment of the
72path name; the
73.Fn _link
74variations operate on the symlink itself.
75.Sh IMPLEMENTATION NOTES
76.Fx Ns 's
77support for POSIX.1e interfaces and features is still under
78development at this time.
79.Sh RETURN VALUES
80.Rv -std
81.Sh ERRORS
82If any of the following conditions occur, these functions shall return -1
83and set
84.Va errno
85to the corresponding value:
86.Bl -tag -width Er
87.It Bq Er EACCES
88Search permission is denied for a component of the path prefix, or the
89object exists and the process does not have appropriate access rights.
90.It Bq Er EBADF
91The
92.Va fd
93argument is not a valid file descriptor.
94.It Bq Er EINVAL
95The ACL type passed is invalid for this file object.
96.It Bq Er ENAMETOOLONG
97A component of a pathname exceeded 255 characters, or an
98entire path name exceeded 1023 characters.
99.It Bq Er ENOENT
100The named object does not exist, or the
101.Va path_p
102argument points to an empty string.
103.It Bq Er ENOMEM
104Insufficient memory available to fulfill request.
105.It Bq Er ENOTDIR
106A component of the path prefix is not a directory.
107.Pp
108Argument
109.Va path_p
110must be a directory, and is not.
111.It Bq Er EOPNOTSUPP
112The file system does not support ACL deletion.
113.It Bq Er EPERM
114The process does not have appropriate privilege to perform the operation
115to delete an ACL.
116.It Bq Er EROFS
117The file system is read-only.

124.Sh STANDARDS
125POSIX.1e is described in IEEE POSIX.1e draft 17.
126Discussion
127of the draft continues on the cross-platform POSIX.1e implementation
128mailing list.
