Alas, sadly this doesn't help. TBH I can live without it, although I'd like to silence the error message unless logging is turned up.

But cdio_log_level_t in > include/cdio/logging.h gives hope that it can be done.) Looking at the linux driver, it seems cdio_info() would be appropriate, but wow, the implementation of the logging functions is scary: ---8<--- void cdio_info (const char format[], ...) GNUC_PRINTF(1,2); ---8<--- And then: --->8--- #if __GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR__ > 4) #define GNUC_PRINTF( format_idx, arg_idx ) \ __attribute__((format (printf, format_idx, arg_idx))) ... #else /* !__GNUC__ */ #define GNUC_PRINTF( format_idx, arg_idx ) #endif /* !__GNUC__ */ --->8--- So if you are not on glibc, then logging is a NOOP, by the look of it. I'm not really sure this logging scheme can work on OpenBSD. I wonder why it was implemented this way. It also looks like there is no way to turn up/down the verbosity of the logging. Or am I mistaken? -- Best Regards Edd Barrett http://www.theunixzoo.co.uk
