ACL_DELETE(3) FreeBSD Library Functions Manual ACL_DELETE(3)

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)

#include <sys/types.h>
#include <sys/acl.h>

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 operate 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 error.

If any of the following conditions occur, these functions shall return -1 and set errno to the corresponding value:
Search permission is denied for a component of the path prefix, or the object exists and the process does not have appropriate access rights.
The fd argument is not a valid file descriptor.
The ACL type passed is invalid for this file object.
A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters.
The named object does not exist, or the path_p argument points to an empty string.
Insufficient memory available to fulfill request.
A component of the path prefix is not a directory.

Argument path_p must be a directory, and is not.

The file system does not support ACL deletion.
The process does not have appropriate privilege to perform the operation to delete an ACL.
The file system is read-only.

acl(3), acl_get(3), acl_set(3), posix1e(3)

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.
