30.Os FreeBSD 4.0
31.Sh NAME
32.Nm acl_delete_def_file ,
33.Nm acl_delete_file_np ,
34.Nm acl_delete_fd_np
35.Nd Delete an ACL from a file
36.Sh SYNOPSIS
37.Fd #include <sys/types.h>
38.Fd #include <sys/acl.h>
39.Ft int
40.Fn acl_delete_def_file "const char *path_p"
41.Ft int
42.Fn acl_delete_file_np "const char *path_p" "acl_type_t type"
43.Ft int
44.Fn acl_delete_fd_np "int filedes" "acl_type_t type"
45.Sh DESCRIPTION
46The
47.Fn acl_delete_def_file ,
48.Fn acl_delete_file_np ,
49and
50.Fn acl_delete_fd_np
51each allow the deletion of an ACL from a file.
52.Fn acl_delete_def_file
53is a POSIX.1e call that deletes the default ACL from a file (normally a
54directory) by name; the other two calls are non-portable extensions that
55allow deleting of arbitrary ACL types from a file/directory by either path
56name, or by file descriptor.
57.Sh IMPLEMENTATION NOTES
58FreeBSD's support for POSIX.1e interfaces and features is still under
59development at this time.
60.Sh RETURN VALUES
61In the event of success, 0 is returned.  In the event of failure, -1 is
62returned, and
63.Va errno
64is set to indicate the error.
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
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.

120.An Robert N M Watson
121.Sh BUGS
122These features are not yet fully implemented.  In particular, the shipped
123version of UFS/FFS does not support storage of additional security labels,
124and so is unable to (easily) provide support for most of these features.
