* File begun on 2007-07-20 by RGerhards (extracted from syslogd.c)
|
|
* This file is under development and has not yet arrived at being fully
|
|
* self-contained and a real object. So far, it is mostly an excerpt
|
|
* of the "old" message code without any modifications. However, it
|
|
* helps to have things at the right place one we go to the meat of it.
