Hi. If I understand right the code, even if log is disabled, I do pay for constructing log messages. Am I right? If so why do you force this?
No, you donot pay.
BOOST_LOG(app) << "testing " << i << '-' << j << '-' << k;
Is the equivalent of:
if ( is_log_enabled(app) ) app_log() << "testing" << i ...;
Best, John
Is it the case however that we'll have to pay the cost of evaluating whatever arguments are supplied (for example if some of them are function calls etc.)? As in: BOOST_LOG(app) << "testing " << fctn() << '-' << j << '-' << k; Will fctn() be called if !is_log_enabled(app)? Thanks, John
