44.In sys/acl.h
45.Ft int
46.Fn acl_delete_def_file "const char *path_p"
47.Ft int

55.Sh DESCRIPTION
56The
57.Fn acl_delete_def_file ,
58.Fn acl_delete_def_link_np ,
59.Fn acl_delete_fd_np ,
60.Fn acl_delete_file_np ,
61and
62.Fn acl_delete_link_np
63each allow the deletion of an ACL from a file.
64The
65.Fn acl_delete_def_file
66function
67is a POSIX.1e call that deletes the default ACL from a file (normally a
68directory) by name; the remainder of the calls are non-portable extensions
69that permit the deletion of arbitrary ACL types from a file/directory
70either by path name or file descriptor.
71The
72.Fn _file
73variations follow a symlink if it occurs in the last segment of the
74path name; the
75.Fn _link
76variations operate on the symlink itself.
77.Sh IMPLEMENTATION NOTES
78.Fx Ns 's
79support for POSIX.1e interfaces and features is still under
80development at this time.
81.Sh RETURN VALUES
82.Rv -std
83.Sh ERRORS
84If any of the following conditions occur, these functions shall return -1
85and set
86.Va errno
87to the corresponding value:
88.Bl -tag -width Er
89.It Bq Er EACCES
90Search permission is denied for a component of the path prefix, or the
91object exists and the process does not have appropriate access rights.
92.It Bq Er EBADF
93The
94.Va fd
95argument is not a valid file descriptor.
96.It Bq Er EINVAL
97The ACL type passed is invalid for this file object.
98.It Bq Er ENAMETOOLONG
99A component of a pathname exceeded 255 characters, or an
100entire path name exceeded 1023 characters.
101.It Bq Er ENOENT
102The named object does not exist, or the
103.Va path_p
104argument points to an empty string.
105.It Bq Er ENOMEM
106Insufficient memory available to fulfill request.
107.It Bq Er ENOTDIR
108A component of the path prefix is not a directory.
109.Pp
110Argument
111.Va path_p
112must be a directory, and is not.
113.It Bq Er EOPNOTSUPP
114The file system does not support ACL deletion.
115.It Bq Er EPERM
116The process does not have appropriate privilege to perform the operation
117to delete an ACL.
118.It Bq Er EROFS
119The file system is read-only.
