This is not hard, but you really need some understanding about what is
going on. The sample code shows everything you need (look at
sample3.c), but you have to understand how the library works. Reading
the documentation is a must.
To understand how this code work, you must understand that it is
event-driven. Basically, you register with the library to tell you when
interesting things happen. And when you ask the library to do
something, it returns immediately and then calls a function you supply
when the operation is complete.
For instance, in sample3.s, you will notice:
rv = ipmi_open_domain("", &con, 1, setup_done, NULL, NULL, NULL,
NULL, 0, NULL);
That creates a "domain" (basically it represents an entire chassis or
system). However, the domain is not ready until "setup_done" is called.
In setup_done, it does:
rv = ipmi_domain_add_entity_update_handler(domain, entity_change,
domain);
That tells the library that if any entity in the domain is
added/removed/changed, call the "entity_change" function. And so forth,
down to sensors and controls.
Further up in the file, you see:
rv = ipmi_sensor_get_reading(sensor, got_thresh_reading, sdata);
This requests a reading from the sensor. When the reading is complete,
got_thresh_reading will be called.
