ACL_DELETE(3) BSD Library Functions Manual ACL_DELETE(3)NAME
acl_delete_def_file, acl_delete_def_link_np, acl_delete_fd_np,
acl_delete_file_np, acl_delete_link_np — delete an ACL from a file
Standard C Library (libc, -lc)
acl_delete_def_file(const char *path_p);
acl_delete_def_link_np(const char *path_p);
acl_delete_fd_np(int filedes, acl_type_t type);
acl_delete_file_np(const char *path_p, acl_type_t type);
acl_delete_link_np(const char *path_p, acl_type_t type);
The acl_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 oper‐
ate on the symlink itself.
FreeBSD's support for POSIX.1e interfaces and features is still under
development at this time.
Upon successful completion, the value 0 is returned; otherwise the
value -1 is returned and the global variable errno is set to indicate the
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 argu‐
ment 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.

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
