/**
* Run webserver operations (without blocking unless in client
* callbacks). This method should be called by clients in combination
* with #MHD_get_fdset if the client-controlled select method is used
* and #MHD_get_timeout().
*
* This function is a convenience method, which is useful if the
* fd_sets from #MHD_get_fdset were not directly passed to `select()`;
* with this function, MHD will internally do the appropriate `select()`
* call itself again. While it is always safe to call #MHD_run (if
* #MHD_USE_INTERNAL_POLLING_THREAD is not set), you should call
* #MHD_run_from_select if performance is important (as it saves an
* expensive call to `select()`).
*
* @param daemon daemon to run
* @return #MHD_SC_OK on success
* @ingroup event
