## 7.7 Multi-Threading

AutoOpts was designed to configure a program for running. This generally happens before much real work has been started. Consequently, it is expected to be run before multi-threaded applications have started multiple threads. However, this is not always the case. Some applications may need to reset and reload their running configuration, and some may use `SET_OPT_xxx()` macros during processing. If you need to dynamically change your option configuration in your multi-threaded application, it is your responsibility to prevent all threads from accessing the option configuration state, except the one altering the configuration.

The various accessor macros (`HAVE_OPT()`, etc.) do not modify state and are safe to use in a multi-threaded application. It is safe as long as no other thread is concurrently modifying state, of course.
