*Define version of the macro that only execute if the log level is above the threshold.

*The compiled versions essentially look like this:

*if (logFlagForThisLogMsg & obsddLogLevel) { execute log message }
|

|
*When OBSLOG_LEVEL_DEF is defined as obsddLogLevel.

*
|
*As shown further below, Lumberjack actually uses a bitmask as opposed to primitive log levels.
|
*This allows for a great amount of flexibility and some pretty advanced fine grained logging techniques.
|
*
|
*Note that when compiler optimizations are enabled (as they are for your release builds),
|
*the log messages above your logging threshold will automatically be compiled out.
|
*
|
*(If the compiler sees OBSLOG_LEVEL_DEF/obsddLogLevel declared as a constant, the compiler simply checks to see
|
* if the 'if' statement would execute, and if not it strips it from the binary.)
|
*
|
*We also define shorthand versions for asynchronous and synchronous logging.
