nabto_device_limit_tcp_tunnel_connections()

DESCRIPTION

Limit concurrent TCP tunnel connections of a specific service type.

Tcp tunnel connections are opened when a TCP connection is established through a TCP tunnel.

If the limit is reached, new TCP tunnels can still be created by the clients as they do not create a connection immediately.

If the limit is decreased after TCP tunnel connections have been made, the existing tcp tunnel connections are not closed but new TCP tunnel connections will be subject to the limit and old tcp tunnel connections count towards the limit.

DECLARATION
