How do I set debug level for a single function?

[adevoss]

When the global debug level is set to "debug" in navit.xml the log file is going to be really big fast. Also see #1485.
So I want to log the debug statements of a single function only.

The following tag in navit.xml does not log anything:
<debug name="navit:speechd_say" dbg_level="debug"/>

What should the tag be to log this function?

Temporary solution is to change relevant debug LOC from debug to error.

Your initial approach doesn't work because speechd_say() lives in the speech_speech_dispatcher module, not navit. The correct tag would be:

<debug name="speech_speech_dispatcher:speechd_say" dbg_level="debug"/>

I agree that this can feel cumbersome, but once you know how to point to modules hopefully it's easier?

There is also a speechd_say function in speech_commandline.c. That's the function I would like to debug.
Would that then be:

<debug name="speech_commandline:speechd_say" dbg_level="debug"/>
