+ * Method called to inform about the egos of this peer.

+ * When used with #GNUNET_IDENTITY_connect, this function is

+ * ego's name changes or if it is deleted. At the end of
+ * the initial pass over all egos, the function is once called
+ * with 'NULL' for @a ego. That does NOT mean that the callback won't
+ * be invoked in the future or that there was an error.
+ *
+ * When used with #GNUNET_IDENTITY_create or #GNUNET_IDENTITY_get,
+ * this function is only called ONCE, and 'NULL' being passed in
+ * @a ego does indicate an error (i.e. name is taken or no default
+ * value is known). If @a ego is non-NULL and if '*ctx'
+ * is set in those callbacks, the value WILL be passed to a subsequent
+ * call to the identity callback of #GNUNET_IDENTITY_connect (if
+ * that one was not NULL).
+ *
+ * When an identity is renamed, this function is called with the
+ * (known) @a ego but the NEW @a name.
+ *
+ * When an identity is deleted, this function is called with the
+ * (known) ego and "NULL" for the @a name. In this case,
+ * the @a ego is henceforth invalid (and the @a ctx should also be
+ * cleaned up).
+ *

+ * @param ctx context for application to store data for this ego
