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

LIBRARY SYNOPSIS DESCRIPTION IMPLEMENTATION NOTES RETURN VALUES ERRORS SEE ALSO STANDARDS HISTORY AUTHORS

Standard C Library (libc, -lc)

#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);

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 operate on the symlink itself.

FreeBSD Ns '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 error.

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.

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.

POSIX.1e support was introduced in FreeBSD 4.0, and development continues.
