Hi,
I’m using the UHD C API from within a C++ application. The reason for that is
that UHD is optionally loaded as dynamic library at runtime through dlopen in
case the user wants to use an ettus device and has the uhd library installed
and therefore I’m limited to only use functions declared as extern C.
I need some custom logging facility for my application as it is GUI based, e.g.
certain errors should end up in alert windows and not in console prints.
However I haven’t found any possibility to implement such logging when
restricted to the C API only. So first question: Did I overlook something? Any
pointer on how to get custom logging working without using the C++ API would be
greatly appreciated.
In the meantime I tried to go a different way. This document
https://files.ettus.com/manual/page_logging.html
<https://files.ettus.com/manual/page_logging.html> tells me, that UHD uses
std::clog for everything using the console logging backend. As no other part of
my application makes use of std::clog I simply redirected std::clog to a custom
std::streambuf instance where I handle the log strings. This works quite well
for the [INFO] log messages, however [ERROR] messages seem to bypass std::clog
and are still printed to the console. Is this intended behaviour or a bug as
the document tells that all console logging goes through std::clog?
Best regards
Janos Buttgereit
