init_egos()

static void init_egos ( void *  cls, struct GNUNET_IDENTITY_Ego *  ego, void **  ctx, const char *  identifier  )

static

If listing is enabled, prints information about the egos.

This function is initially called for all egos and then again whenever a ego's identifier changes or if it is deleted. At the end of the initial pass over all egos, the function is once called with 'NULL' for '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 'ego' does indicate an error (i.e. name is taken or no default value is known). If '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) ego but the NEW identifier.

When an identity is deleted, this function is called with the (known) ego and "NULL" for the 'identifier'. In this case, the 'ego' is henceforth invalid (and the 'ctx' should also be cleaned up).

Parameters

cls	closure
ego	ego handle
ctx	context for application to store data for this ego (during the lifetime of this process, initially NULL)
identifier	identifier assigned by the user for this ego, NULL if the user just deleted the ego and it must thus no longer be used
