- * Name: lowsyslog
- *
- * Description:
- *   syslog() generates a log message. The priority argument is formed by
- *   ORing the facility and the level values (see include/syslog.h). The
- *   remaining arguments are a format, as in printf and any arguments to the
- *   format.
- *
- *   This is a non-standard, low-level system logging interface.  The
- *   difference between syslog() and lowsyslog() is that the syslog()
- *   interface writes to the syslog device (usually fd=1, stdout) whereas
- *   lowsyslog() uses a lower level interface that works even from interrupt
- *   handlers.
