I'm new to multi-threaded programming. So I apologize for aksing what is
possibly a silly question.

Will below code give me the behaviour of what is commonly called a
"spinlock"?

  boost::unique_lock< boost::shared_mutex >
    guard( mutex, boost::try_to_lock );

  if ( !guard.owns_lock() ) {
    while ( !guard.try_lock() ) {
      boost::thread::yield();
    }
  }

  // access data

Cheers,

Moritz
