Subject: [PATCH v2 05/10] tools lib traceevent: Remove call to exit() from tep_filter_add_filter_str()
Date: Mon,  8 Apr 2019 18:23:35 +0300	[thread overview]
Message-ID: <20190408152340.12450-6-tstoyanov@vmware.com> (raw)
In-Reply-To: <20190408152340.12450-1-tstoyanov@vmware.com>

This patch removes call to exit() from tep_filter_add_filter_str(). A
library function should not force the application to exit. In the
current implementation tep_filter_add_filter_str() calls exit() when a
special "test_filters" mode is set, used only for debugging purposes.
When this mode is set and a filter is added - its string is printed to
the console and exit() is called. This patch changes the logic - when in
"test_filters" mode, the filter string is still printed, but the exit()
is not called. It is up to the application to track when "test_filters"
mode is set and to call exit, if needed.
