isc_result_t ns_log_setdefaultchannels

(

lcfg

)

Initialize the logging system and set up an initial default logging default configuration that will be used until the config file has been read.

If 'safe' is true, use a default configuration that refrains from opening files. This is to avoid creating log files as root.
