/* This structure represents the files that will have log
|
|
* copies printed.
|
|
* RGerhards 2004-11-08: Each instance of the filed structure
|
|
* describes what I call an "output channel". This is important
|
|
* to mention as we now allow database connections to be
|
|
* present in the filed structure. If helps immensely, if we
|
|
* think of it as the abstraction of an output channel.
|
|
* rgerhards, 2005-10-26: The structure below provides ample
|
|
* opportunity for non-thread-safety. Each of the variable
|
|
* accesses must be carefully evaluated, many of them probably
|
|
* be guarded by mutexes. But beware of deadlocks...
|
|
* rgerhards, 2007-08-01: as you can see, the structure has shrunk pretty much. I will
|
|
* remove some of the comments some time. It's still the structure that controls much
|
|
* of the processing that goes on in syslogd, but it now has lots of helpers.
