Static Public Member Functions
static void	print (std::ostream &os, std::ostringstream &sos)
	Writes sos's buffered content to os, serializing concurrent writers under FST_THREADED via a shared mutex.

Static Private Member Functions
static std::mutex &	get_io_mutex ()
	Returns the process-wide mutex guarding concurrent output via print() (FST_THREADED builds only).

Detailed Description

Serializes textual reporting from concurrent threads.

The class holds no state and is never instantiated (the constructor is private); it exists only as the scope of the static print() service and of the mutex that guards it. Every output produced from code that may run inside a threaded search must go through syncout::print() – writing to std::cout directly from several threads interleaves characters and, in the worst case, stalls the reporting.
