It appears to have been removed in version 4.2, last appears in the current git on tag remote/origin/v4.1-stable:
core-net/server.c line 52:
lws_json_dump_vhost(const struct lws_vhost *vh, char *buf, int len)
It looks like in 4.3.99 (my current version, and main as of date) that the conn_stat struct has been removed so that information is no longer available, also there were many casts needed to get it to compile without disabling narrowing conversion errors, but here it is resuited for use:
Add this to service.c when compile libwebsockets:
