LIBRARY
library “libc”
SYNOPSIS
#include
<sys/types.h>
#include <sys/acl.h>
int
acl_delete_def_file
(const
char *path_p);
int
acl_delete_def_link_np
(const
char *path_p);
int
acl_delete_fd_np
(int
filedes, acl_type_t
type);
int
acl_delete_file_np
(const
char *path_p, acl_type_t
type);
int
acl_delete_link_np
(const
char *path_p, acl_type_t
type);
DESCRIPTION
Theacl_delete_def_file
(),
acl_delete_def_link_np
(),
acl_delete_fd_np
(),
acl_delete_file_np
(),
and
acl_delete_link_np
()
each allow the deletion of an ACL from a file. The
acl_delete_def_file
() function is a POSIX.1e call that
deletes the default ACL from a file (normally a directory) by name; the
remainder of the calls are non-portable extensions that permit the deletion of
arbitrary ACL types from a file/directory either by path name or file
descriptor. The
_file
()
variations follow a symlink if it occurs in the last segment of the path name;
the
_link
()
variations operate on the symlink itself.
IMPLEMENTATION NOTES
FreeBSD's support for POSIX.1e interfaces and features is still under development at this time.
RETURN VALUES
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
ERRORS
If any of the following conditions occur, these functions shall return -1 and set errno to the corresponding value:
- [
EACCES
] - Search permission is denied for a component of the path prefix, or the object exists and the process does not have appropriate access rights.
- [
EBADF
] - The fd argument is not a valid file descriptor.
- [
EINVAL
] - The ACL type passed is invalid for this file object.
- [
ENAMETOOLONG
] - A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters.
- [
ENOENT
] - The named object does not exist, or the path_p argument points to an empty string.
- [
ENOMEM
] - Insufficient memory available to fulfill request.
- [
ENOTDIR
] - A component of the path prefix is not a directory.
Argument path_p must be a directory, and is not.
- [
EOPNOTSUPP
] - The file system does not support ACL deletion.
- [
EPERM
] - The process does not have appropriate privilege to perform the operation to delete an ACL.
- [
EROFS
] - The file system is read-only.

STANDARDS
POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion of the draft continues on the cross-platform POSIX.1e implementation mailing list. To join this list, see the FreeBSD POSIX.1e implementation page for more information.
HISTORY
POSIX.1e support was introduced in FreeBSD 4.0, and development continues.
