# All the YAZ-logging functions other than yaz_log_mask_str() have
# side-effects, which makes them painful to write tests for.  At the
# moment, I think we have better ways to spend the time, so these
# functions remain untested:
#	int yaz_log_module_level(const char *name);
#	void yaz_log_init(int level, const char *prefix, const char *name);
#	void yaz_log_init_file(const char *fname);
#	void yaz_log_init_level(int level);
#	void yaz_log_init_prefix(const char *prefix);
#	void yaz_log_time_format(const char *fmt);
#	void yaz_log_init_max_size(int mx);
#	void yaz_log(int level, const char *str);
# But if anyone feels strongly enough about this to want to fund the
# creation of a rigorous YAZ-logging test suite, please get in touch
# :-)
