access the global logger object by importing "log" from this module<br>

This method should be called from handlers when an exception is<br>

encountered during an <a href="#PyLinkChannelLogger-emit">emit</a>() call. If raiseExceptions is false,<br>
|

exceptions get silently ignored. This is what is mostly wanted<br>
|
|
|
|
|
for a logging system - most users will not care about errors in<br>
|
|
|
|
|
the logging system, they are more interested in application errors.<br>
|
|
|
|
|
You could, however, replace this with a custom handler if you wish.<br>
|
|

The record which was being processed is passed in to this method.</tt></dd></dl>

this and the record is then dropped. Returns a zero value if a record<br>
