In order to log these custom types, simply override an operator<< function, the same as if you would print the custom type to std::cout. log4c was successfully compiled and run on the following platforms: log4c should compile and run on the following platforms: The following software is needed to generate log4c: For the moment, log4c uses specific GCC extensions, like attribute, so you will need GCC to compile it. More formally: The inherited level for a given logger C, is equal to the first non-null level in the logger hierarchy, starting at C and proceeding upwards in the hierarchy towards the root logger. A full example can be seen in the format-string.cpp file. This capability assumes that the logging space, that is, the space of all possible logging statements, is categorized according to some developer-chosen criteria. The LOG4CXX_DEBUG and similar macros have a cost of an in-lined null pointer check plus an integer comparison when the logger not currently enabled for that level. As for protecting against Log4j on the server side, its laughably simple. Keep an eye on your inbox! Legal The output of a log statement of logger C will go to all the appenders in C and its ancestors.
