create_member()

struct GNUNET_MESSENGER_Member* create_member	(	struct GNUNET_MESSENGER_MemberStore *	store,
		const struct GNUNET_ShortHashCode *	id
	)

If the creation fails, NULL gets returned.

Parameters

[in,out]	store	Member store
[in]	id	Member id or NULL

Returns

New member or NULL

iterate_member_sessions()

int iterate_member_sessions	(	struct GNUNET_MESSENGER_Member *	member,
		GNUNET_MESSENGER_MemberIteratorCallback	it,
		void *	cls
	)

Iterate through all member sessions currently connected to a given member and call the provided iterator callback with a selected closure.

The function will return the amount of member sessions it iterated through.

Parameters

[in,out]	member	Member
[in]	it	Iterator callback
[in,out]	cls	Closure

Returns

Amount of sessions iterated through
