A timestamp - is taken right after returning from the event sleep, and before - dispatching any event sources. The <parameter>event</parameter> - parameter specifies the event loop object to retrieve the timestamp - from. The <parameter>clock</parameter> parameter specifies the clock to - retrieve the timestamp for, and is one of - <constant>CLOCK_REALTIME</constant> (or equivalently - <constant>CLOCK_REALTIME_ALARM</constant>), - <constant>CLOCK_MONOTONIC</constant>, or - <constant>CLOCK_BOOTTIME</constant> (or equivalently - <constant>CLOCK_BOOTTIME_ALARM</constant>), see - <citerefentry project='man-pages'><refentrytitle>clock_gettime</refentrytitle><manvolnum>2</manvolnum></citerefentry> - for more information on the various clocks. The retrieved - timestamp is stored in the <parameter>usec</parameter> parameter, - in µs since the clock's epoch. If this function is invoked before - the first event loop iteration, the current time is returned, as - reported by <function>clock_gettime()</function>. To distinguish - this case from a regular invocation the return value will be - positive, and zero when the returned timestamp refers to an actual - event loop iteration.</para> - </refsect1> - - <refsect1> - <title>Return Value</title> - - <para>If the first event loop iteration has not run yet - <function>sd_event_now()</function> writes current time to - <parameter>usec</parameter> and returns a positive return value. - Otherwise, it will write the requested timestamp to <parameter>usec</parameter> - and return 0.
