ACL_DELETE(3)		     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

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 de-
     velopment 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  per-
			form 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 in-
     formation.

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