as replied earlier, if your doing nothing but consuming events, you can just block instead of sleep:

con:pop(1)


there is also a msleep function that you can call the same way you do console_log, it takes milli seconds as its arg. Note this should NOT be used when you have a script running as a session, only when you are running an api script.

Got a few more questions about running LUA scripts, please forgive me, I'm an absolute newbie with LUA.

If I want to subscribe to a custom event, and I use


con = freeswitch.EventConsumer("CUSTOM my::event");


I get an error. Is this because I must subscribe to the CUSTOM (only) event, and then filter out the events using the Event-Subclass myself? Or am I missing something in the syntax of the subscribe?


Also, if I do not have a freeswitch.Session, what is the best way to have my LUA script sleep? I want a functionality, where a statement inside my LUA script gets iterated every 30 seconds. My program does not use a session, so I cannot use session:execute("sleep","1000"), as suggested in the wiki. I tried api::sleep(30000) and a few other combinations with execute but no luck Sad.


Thanks.

Quote:

now you have a consumer obj

every time you call con:pop() with no arg you will either get an event or
nil when there are no events to consume.
every time you call con:pop(1) the consumer object will block until there is
an event.

So you use the first way in conjunction with some other lock to do async or
the 2nd way you do a dedicated blocking loop.


FYI, I added this information to the wiki page for freeswitch.EventConsumer.

I know before I asked about blocking for an event, and maybe I should have created a new topic..

but now I want to actually sleep (rather than block) for a set time frame...this app will not be consuming events.


can I get an example of how to use msleep in a lua script? This lua script will be running in the background, and not part of a session or event consumer. Thanks.

Lua has no sleep or pause ... if you read thru the lua wiki they show you various ways to accomplish that.

It takes 2 args, not one to specify the subclass

Thanks, the freeswitch.msleep(5000) works!

Any comment about the first Q...

con = freeswitch.EventConsumer("CUSTOM my::event");

I get an error. Is this because I must subscribe to the CUSTOM
(only) event, and then filter out the events using the Event-
Subclass myself? Or am I missing something in the syntax of the
subscribe?


Thanks Michael for your help...
