I am transferred a source from friend for study. inside main.c,
there is a function named setSensiPars called (setSensiPars(3,0)), I
tried to trace its definition by right-clicked on it and choose go to
definition of &amp;#39;setSensiPars&amp;#39; but I get the msg</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Cannot find definition of extern function, reference only</title><link>https://community.arm.com/thread/109710?ContentTypeID=1</link><pubDate>Tue, 19 Mar 2019 09:52:16 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:9235d728-a787-4b70-8534-98e87f8d2af3</guid><dc:creator>Andrew Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
You could use your toolchain&amp;#39;s library manager to find what
functions are exposed by the library.&lt;/p&gt;

&lt;p&gt;
You could also look in the Linker map to see if it tells you where
the definition came from.&lt;/p&gt;

&lt;p&gt;
You haven&amp;#39;t stated what toolchain you&amp;#39;re using, so can&amp;#39;t be more
specific.&lt;/p&gt;

Thank Neil for opinion.&lt;/p&gt;

&lt;p&gt;
The source actually is inherited from a company and it is not easy
to contact.&lt;br /&gt;
I confirm that there is a lib file in the source, your idea may be
correct&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Cannot find definition of extern function, reference only</title><link>https://community.arm.com/thread/71175?ContentTypeID=1</link><pubDate>Tue, 19 Mar 2019 03:11:27 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:4b94ac55-b9bb-4cf5-9834-fc8071f0a37f</guid><dc:creator>Andrew Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
Why don&amp;#39;t you just ask that friend?&lt;/p&gt;

&lt;p&gt;
Sounds like the definition must be in a library ...&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
