◆ multi_process_post()

bool multi_process_post	(	struct multi_context *	m,
		struct multi_instance *	mi,
		const unsigned int	flags
	)

Perform postprocessing of a VPN tunnel instance.

After some VPN tunnel activity has taken place, the VPN tunnel's state may need updating and some follow-up action may be required. This function controls the necessary postprocessing. It is called by many other functions that handle VPN tunnel related activity, such as multi_process_incoming_link(), multi_process_outgoing_link(), multi_process_incoming_tun(), multi_process_outgoing_tun(), and multi_process_timeout(), among others.

Parameters

m	- The single `multi_context` structure.
mi	- The `multi_instance` of the VPN tunnel to be postprocessed.
flags	- Fast I/O optimization flags.

Returns

True, if the VPN tunnel instance mi was not closed due to a signal during processing.
False, if the VPN tunnel instance mi was closed.

This function should be called after a push-update and old_ip/old_ipv6 are the previous addresses of the client in ctx->options.ifconfig_local and ctx->options.ifconfig_ipv6_local.
