<p>There are some other flags defined in logging.cc. Please grep the
source code for "DEFINE_" to see a complete list of all flags.
+<p>You can also modify flag values in your program by modifying global
+variables <code>FLAGS_*</code> . Most settings start working
+immediately after you update <code>FLAGS_*</code> . The exceptions are
+the flags related to destination files. For example, you might want to
+set <code>FLAGS_log_dir</code> before
+calling <code>google::InitGoogleLogging</code> . Here is an example:
+
+<pre>
+ LOG(INFO) << "file";
+ // Most flags work immediately after updating values.
+ FLAGS_logtostderr = 1;
+ LOG(INFO) << "stderr";
+ FLAGS_logtostderr = 0;
+ // This won't change the log destination. If you want to set this
+ // value, you should do this before google::InitGoogleLogging .
+ FLAGS_log_dir = "/some/log/directory";
+ LOG(INFO) << "the same file";
+</pre>
