I'm not sure what you are saying. First of all, that is not a spin loop
looking for information. It blocks until a message comes in or a timer
goes off. It will tend to use very little CPU unless you open a *lot*
of domains.
Second, you really don't need two threads here. The function of
second_thread() is non-blocking and will return immediately. You can
simply call (not spawn a thread) second_thread(), then spawn
first_thread(). If the "main" thread here after returning from
Ipmi_Task::open(), you can just call the operation loop there and not
spawn a thread at all.
Third, is handle_domain() printing anything? Also, as I have said
before, that function will be called when the connection is set up, not
when it has finished setting up/scanning the domain. It is useless to
iterate the entities at that point in the program, because there won't
be any until it has set up the domain. So you program here will
basically print "Domain open error" and then not do anything else.
You need a return after ipmi_domain_iterate_entities or it will always
print the error. And you should probably print the error value.
You need iterate the domains in a different place. Look at the later
parameters in ipmi_domain_open. There is one that is called when the
domain is fully up. Use that one to iterate the entities.
