Global rc_openlog (char const *ident): New code should call openlog(3) directly. radcli emits all messages via syslog(3); opening the log with your application's own ident and facility before the first radcli call is sufficient. This function is a thin wrapper around openlog() retained for source compatibility with freeradius-client and radiusclient-ng.
Global rc_setdebug (int debug): Prefer setting clientdebug in the configuration file (rc_read_config()) or rc_add_config(). Using this function bypasses the config file and is retained only for source compatibility with freeradius-client and radiusclient-ng.
