These functions are non-portable extensions that permit the deletion of arbitrary ACL types from a file/directory either by path name or file descriptor. The .Fn _file variations follow a symlink if it occurs in the last segment of the path name; the .Fn _link variations operate on the symlink itself. .Sh RETURN VALUES .Rv -std .Sh ERRORS If any of the following conditions occur, these functions shall return -1 and set .Va errno to the corresponding value: .Bl -tag -width Er .It Bq Er 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. .It Bq Er EBADF The .Va fd argument is not a valid file descriptor. .It Bq Er EINVAL The ACL type passed is invalid for this file object. .It Bq Er ENAMETOOLONG A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters. .It Bq Er ENOENT The named object does not exist, or the .Va path_p argument points to an empty string. .It Bq Er ENOMEM Insufficient memory available to fulfill request. .It Bq Er ENOTDIR A component of the path prefix is not a directory. .Pp Argument .Va path_p must be a directory, and is not. .It Bq Er EOPNOTSUPP The file system does not support ACL deletion. .It Bq Er EPERM The process does not have appropriate privilege to perform the operation to delete an ACL. .It Bq Er EROFS The file system is read-only. .El .Sh SEE ALSO .Xr acl 3 , .Xr acl_get 3 , .Xr acl_set 3 , .Xr posix1e 3 .Sh STANDARDS POSIX.1e is described in IEEE POSIX.1e draft 17. .Sh AUTHORS .An Michael Smith .An Robert N M Watson
