Detailed Description

These macros specify a log point in the code from which the given message can be logged with the given log level.

The macro generates code which first tests whether the log point is active before generating the message, thus minimizing the time overhead for logging. The active() status is tested without locking, so if multiple threads are sharing a log point, or if logging is reconfigured while threads are running, then that could be considered a violation of mutual exclusion. Concurrency checkers like helgrind may complain about this in multithreaded code.

The MSG argument must be in parentheses, so that it can be a variable argument list. The whole argument list is passed to LogMessage::format() to generate the message string.

DLOG(("the current value of pi is %f", pi));

Since LogMessage::format() returns the LogMessage instance, further text can be added to the message with the streaming operator<<, like so:

DLOG(("pi = ") << pi);

The macro forms with the T suffix include a tags string which will be associated with the LogContext:

DLOGT("samples,variable_conversion",

("convert %s: calculating, ", vname) << nvar << " processed.");

Tags just allow one more way to discriminate among log points. Log points can be activated or deactivated according to their tags through a LogConfig.
