Detailed Description

The slog class is used to stream messages to the system logging fascility. system logging fascility class.

A default slog object is used to avoid confusion with the native syslog fascility and to imply a logical relationship to the C++ clog().

The key difference is that the slog object sends it's output to the system logging daemon (typically syslogd) rather than through stderr. slog can be streamed with the << operator just like clog; a default slog object is pre-initialized, and you stream character data to it.

The slog allows one to specify logging levels and other properties through the () operators. Hence, once can do:

 slog("mydaemon", SLOG_DAEMON, SLOG_EMERGENCY) << I just died << endl; 

or things like:

 slog("mydaemon", SLOG_DAEMON); 
 slog(SLOG_INFO) << "daemon initalized" << endl; 

The intent is to be as common-place and as convenient to use as the stderr based clog facility found in C++, and this is especially useful for C++ daemons.
