Detailed Description
Log is an easy to use thread safe logging library, with 9 levels of logging (Nice::LFATAL, Nice::LERROR, Nice::LWARNING, Nice::LINFO, Nice::LNOTICE, Nice::LDEBUG). 3 classes of log macros, plain string logging, c++ iostream logging and optional output redirection.

- 2012-08-10 11:04:58 AM The logging class is based on std::iostream using the class Nice::LogStreamBuf derived from std::ostreambuf. There are 6 levels of logging defined Nice::LFATAL, Nice::LALERT, Nice::LCRITICAL, Nice::LERROR, Nice::LWARNING, Nice::LINFO, Nice::LNOTICE, Nice::LDEBUG, Nice::LTRACE. The logging level can be set at runtime or compile time. At compile time:
#define Nice::LDEBUG // all loglevels #define NICE_DEBUG // Nice::LFATAL, Nice::LALERT, Nice::LCRITICAL, Nice::LERROR, Nice::LWARNING, Nice::LNOTICE, Nice::LINFO, Nice::LDEBUG #define NICE_LOG_DEBUGLEVEL7 // Nice::LFATAL, Nice::LALERT, Nice::LCRITICAL, Nice::LERROR, Nice::LWARNING, Nice::LNOTICE, Nice::LINFO #define NICE_LOG_DEBUGLEVEL6 // Nice::LFATAL, Nice::LALERT, Nice::LCRITICAL, Nice::LERROR, Nice::LWARNING, Nice::LNOTICE #define NICE_LOG_DEBUGLEVEL5 // Nice::LFATAL, Nice::LALERT, Nice::LCRITICAL, Nice::LERROR, Nice::LWARNING #define NICE_LOG_DEBUGLEVEL4 // Nice::LFATAL, Nice::LALERT, Nice::LCRITICAL, Nice::LERROR #define NICE_LOG_DEBUGLEVEL3 // Nice::LFATAL, Nice::LALERT, Nice::LCRITICAL #define NICE_LOG_DEBUGLEVEL2 // Nice::LFATAL, Nice::LALERT #define NICE_LOG_DEBUGLEVEL1 // Nice::LFATAL
