+.Sh DESCRIPTION
+The
+.Fn acl_delete_def_file ,
+.Fn acl_delete_file_np ,
+and
+.Fn acl_delete_fd_np
+each allow the deletion of an ACL from a file.
+.Fn acl_delete_def_file
+is a POSIX.1e call that deletes the default ACL from a file (normally a
+directory) by name; the other two calls are non-portable extensions that
+allow deleting of arbitrary ACL types from a file/directory by either path
+name, or by file descriptor.
+.Sh IMPLEMENTATION NOTES
+.Fx Ns 's
+support for POSIX.1e interfaces and features is still under
+development at this time.
+.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

+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
