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