Есть задача: писать каждый тип сообщений (предупреждения, ошибки, инфо и дебаг) каждый в свой файл.
enum severity_level
{
debug,
info,
warning,
error,
nolog
};
void TLogger::AddFileLog(severity_level level, const std::string & fname)
{
namespace keywords = boost::log::keywords;
boost::log::add_file_log
(
keywords::file_name = fname, /*< file name pattern >*/
keywords::rotation_size = sizelog, /*< rotate files every 10 MiB... >*/
keywords::format = "[%TimeStamp%]: %Message%",/*< log record format >*/
keywords::filter=[&]()->bool{return level==loglevel;}
);
}
