The output can be streamed to stderr, to a file, - * to a logging daemon, or it can be set to be "silent". - * If logging records are output to a file, the file can be set - * to a maximum size and repeatedly split into new files. The - * log file size can be limited at any logging point (i.e., - * application, client logging daemon, or server logging daemon) - * by specifying the -i <sample_interval_in_secs> and -m - * <max_size_in_KB> options for the Logging_Strategy class in a - * svc.conf file. - * - * By default, two logfiles are generated. It's possible, however, to - * generate as many logfiles as necessary to store all the - * information. To achieve this, it is only necessary to indicate the - * maximum size of the logfiles via the -m option and the process will - * generate automatically the logfiles. You can control the total - * number of logfiles created via the -n option. - * - * By using the -o option we can also choose the mode of organization - * of the files, e.g., the first one is the normal used in Unix - * systems (when cron rotates the logs it keeps the lowest number the - * most recent one), the second is for increasing speed (we only - * create a new log file, and don't rotate the others (fewer accesses - * to disk)). - */ -class ACE_Export ACE_Logging_Strategy : public ACE_Service_Object -{ -public: - /// Constructor. - ACE_Logging_Strategy (void); - - /// Dynamic linking initialization hook. - virtual int init (int argc, ACE_TCHAR *argv[]); - - /// Dynamic linking termination hook. - virtual int fini (void); - - /** - * Timeout handler which tests logfile size.
