[Freeswitch-dev] Question about switch_cond_next()

Hi, would someone clarify this for me please Is it right to say that switch_cond_next() does only one thing which is to put the current thread to sleep for a period of time (1 second) ? Is it equivalent to, let's say, Thread.Sleep(xxx); or it also does something else besides putting the current thead to sleep ? Is switch_cond_yield the same as switch_cond_next, except that switch_cond_yield accepts parameter as the input interval ? Thanks Regards Alex To
