determine the state the event loop is currently in. It returns one

- <para>All four functions take, as the first argument, the event
- loop object <parameter>event</parameter> that has been created
- with <function>sd_event_new()</function>. The timeout for
- <function>sd_event_wait()</function> is specified in
- <parameter>usec</parameter> in milliseconds. <constant>(uint64_t)
- -1</constant> may be used to specify an infinite timeout.</para>
+ <para><function>sd_event_get_iteration()</function> may be used to determine the current iteration of the event
+ loop. It returns an unsigned 64bit integer containing a counter that increases monotonically with each iteration of
+ the event loop, starting with 0. The counter is increased at the time of the
+ <function>sd_event_prepare()</function> invocation.</para>
