144 * This function is initially called for all egos and then again
145 * whenever a ego's identifier changes or if it is deleted. At the
146 * end of the initial pass over all egos, the function is once called
147 * with 'NULL' for 'ego'. That does NOT mean that the callback won't
148 * be invoked in the future or that there was an error.
150 * When used with 'GNUNET_IDENTITY_create' or 'GNUNET_IDENTITY_get',
151 * this function is only called ONCE, and 'NULL' being passed in
152 * 'ego' does indicate an error (i.e. name is taken or no default
153 * value is known). If 'ego' is non-NULL and if '*ctx'
154 * is set in those callbacks, the value WILL be passed to a subsequent
155 * call to the identity callback of 'GNUNET_IDENTITY_connect' (if
156 * that one was not NULL).
158 * When an identity is renamed, this function is called with the
159 * (known) ego but the NEW identifier.
161 * When an identity is deleted, this function is called with the
162 * (known) ego and "NULL" for the 'identifier'. In this case,
163 * the 'ego' is henceforth invalid (and the 'ctx' should also be
