*int ll2_rename_user (struct ll2_context *__context__, const char *__user__,
		      const char *__newname__, char **__error__);*

== DESCRIPTION

Changing user name from _user_ to _newname_ of one entry in
database, which is defined by _context_. All other entries with the user _user_

will be taken.

--------------------------------------
char    *error = NULL;
const   char *user = "root";

int ret = ll2_rename_user (NULL, user, new_user, &error);
--------------------------------------

== RETURN VALUE
