-/* The following functions will support advanced output module
- * multithreading, once this is implemented. Currently, we
- * include them as hooks only. The idea is that we need to guard
- * some msg objects data fields against concurrent access if
- * we run on multiple threads. Please note that in any case this
- * is not necessary for calls from INPUT modules, because they
- * construct the message object and do this serially. Only when
- * the message is in the processing queue, multiple threads may
- * access a single object. Consequently, there are no guard functions
- * for "set" methods, as these are called during input. Only "get"
- * functions that modify important structures have them.
- * rgerhards, 2007-07-20
- * We now support locked and non-locked operations, depending on
- * the configuration of rsyslog. To support this, we use function
- * pointers. Initially, we start in non-locked mode. There, all
- * locking operations call into dummy functions. When locking is
- * enabled, the function pointers are changed to functions doing
- * actual work. We also introduced another MsgPrepareEnqueue() function
- * which initializes the locking structures, if needed. This is
- * necessary because internal messages during config file startup
- * processing are always created in non-locking mode. So we can
- * not initialize locking structures during constructions. We now
- * postpone this until when the message is fully constructed and
- * enqueued. Then we know the status of locking. This has a nice
- * side effect, and that is that during the initial creation of
- * the Msg object no locking needs to be done, which results in better
- * performance. -- rgerhards, 2008-01-05
