* @file SMLog.hpp
* @author Schlund + Partner AG
* @brief Syslog Macro Log: Simple logging based on compiler macros and syslog(3)
*
* Synopsis:
* @code
* #include <ui-utilcpp/SMLog.hpp>
* @endcode
*
* Each prirority level (see syslog(3)) gets its own compiler macro, which can be used
* rather straightforward in the source; the argument of the macro may include stream piping.
* For example:
*
* SM_LOGNOTICE("I have noticed something: " << something)
*
* Logs can be turned off at compile time (giving full run time advantage, as the code is removed)
* with a threshold. Additionally, you can give the facility, and additional text at compile time.
* For example:
*
* c++ ... -DSM_LOGLEVEL=5 -DSM_LOGADD="getpid()" -DSM_LOGFACILITY="ost::SLOG_USER"
*
* eliminates all log messages with priority higher than 5, giving the process id as additional
* information
*
* Logging itself is done CommonC++'s Slog. It is common to make the following
* configuration (Note: currently, the facility must be given when compiling):
*
* ost::slog.open(LOGPREFIX, FACILITY); // Set prefix and syslog(3) facility.
*
* ost::slog.clogEnable(true); // En- or disable logging to "clog"
*
* levels as defined in syslog(3).
*
* The log strings automatically get several additional information, like source file name,
* line number, process id, etc.
*
