The closelog_r() does the same thing as closelog(3) but in a multithread- safe way and takes an additional pointer to a syslog_data structure. The setlogmask () function sets the log priority mask to maskpri and returns the previous mask.
The logopt argument is a bit field specifying logging options, which is formed by OR'ing one or more of the following values: LOG_CONS If syslog() cannot pass the message to syslogd(8) it will attempt to write the message to the console (``/dev/console'').
