Subject: [Xenomai-help] Analogy cmd_write example explanation
Date: Wed, 10 Mar 2010 16:26:04 +0100 [thread overview]
Message-ID: <4B97BA0C.9000702@domain.hid> (raw)
Hello. I'm looking into the analogy cmd_write example.
I'm not sure I understand the reason for the rt_task_set_mode() function
call into the data acquisition loop (lines 413 or 464 in the code
shipped with xenomai 2.5.1).
I do not understand why we have to set the primary mode at every
iteration, when we set it before for the task (line 380).
Is it because the dump_function() uses system calls that can make the
task to switch to secondary mode, or there is a deeper reason I'm missing?
Thanks. Cheers,
--
Daniele
