/* Whenever a log output starts a new log, such as opening the console for the
|
||
|
* first time or rotating to a new log file, or even at a regular interval, it
|
||
|
* emits a "prolog" that starts with the current date/time, then a series of
|
||
|
* log messages generated by invoking all the log_prolog triggers.
|
||
|
*
|
||
|
* The log_prolog trigger functions call the standard logging API to produce
|
||
|
* their output, but the logging system uses an internal trick to ensure that
|
||
|
* the their messages only go to the log output that invoked them, so for
|
||
|
* example, when a log file rotates, the prolog only gets written into the new
|
||
|
* file, and not into the console log as well.
