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

LIBRARY

Standard C Library (libc, -lc)

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

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.

IMPLEMENTATION NOTES

FreeBSD's support for POSIX.1e interfaces and features is

still under
development at this time.

RETURN VALUES

The function returns the value 0 if successful; 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 compo

nent 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 de

scriptor.

[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 charac

ters.

[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.

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

for more
information.

HISTORY

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

ment continues.
