◆ generate_free_member_id()

int generate_free_member_id	(	struct GNUNET_ShortHashCode *	id,
		const struct GNUNET_CONTAINER_MultiShortmap *	members
	)

Tries to generate an unused member id and store it into the id parameter.

A map containing all currently used member ids is used to check against.

Parameters

[out]	id	New member id
	members	Map of member ids

Returns: GNUNET_YES on success, GNUNET_NO on failure
