\subsection{Detailed Description}
A dns subsystem for Libevent. 

The $<$\hyperlink{evdns_8h}{evdns.\+h}$>$ header is deprecated in Libevent 2.\+0 and later; please use $<$event2/evdns.\+h$>$ instead. Depending on what functionality you need, you may also want to include more of the other event2/$\ast$.h headers.
