Would it be possible (and how) to access the bindings inside nginx via  
Lua?  
for an experiment I’d like to change the listening port of a running  
nginx  
process.

I can’t really speak of Lua, but given the nginx architecture it’s  
highly unlikely to be ever possible. Listen sockets are created  
by master process and inherited by workers. In most cases,  
workers just can’t open listening sockets due to security  
restrictions.

I’d still like to try, can you point me where a worker binds to the  
inherited values?

It just have them in the cycle-\>listening array.
