* These syslog() related routines use syslogd. They replace the old
|
|
* syslog() routines in the lbsd library.
|
|
*
|
|
* If syslogd is not found, syslog() calls old_syslog with the handle it
|
|
* would have passed to syslogd. If you are sure your program will have
|
|
* syslogd available when it is run, you can replace old_syslog() with
|
|
* a dummy routine that does nothing and returns. This will make your
|
|
* program smaller.
|
|
*
|
|
* syslogd is built into init and is automatically started by it. I
|
|
* recommend that you use init with GNO/ME 2.0
