logging facilities (with rt support)
See qi::log Developer Guide for a global overview of the logging system.

How to use log:

  #include <cstdlib>  //for atexit
  #include <qi/log.hpp>
  void main() {
    // first init the log system
    qi::log::init();
    atexit(qi::log::destroy);

    // c syntax
    qiLogInfo("foo.bar", "%s kick %s" , "foo", "bar");
    qiLogInfo("foo.bar", "%s punch %s", "bar", "foo");
    qiLogWarning("pif.paf", "pif kiss paf %d time", 42);

    // c++ syntax
    qiLogInfo("tic.tac") << "tic, " << "tac " << 42 << " times";
    qiLogVerbose("foo.bar") << "bar punch " << "foo";
  }

Warning:

You should call qi::log::init at the start of your program and register a handler when the program exit to destroy the logger.
