Function Documentation

int eap_fast_add_pac	(	struct eap_fast_pac **	pac_root,
		struct eap_fast_pac **	pac_current,
		struct eap_fast_pac *	entry
	)

eap_fast_add_pac - Add a copy of a PAC entry to a list : Pointer to PAC list root pointer : Pointer to the current PAC pointer : New entry to clone and add to the list Returns: 0 on success, -1 on failure

This function makes a clone of the given PAC entry and adds this copied entry to the list (pac_root). If an old entry for the same A-ID is found, it will be removed from the PAC list and in this case, pac_current entry is set to NULL if it was the removed entry.
