       Attempts  host  name  resolution  for  the given hostname with length namelen. When a result is ready the
       handler  of  contp  is  called  with  the  TS_EVENT_HOST_LOOKUP  event  and  a  TSHostLookupResult.   Use
       TSHostLookupResultAddrGet() to retrieve the resulting address from the TSHostLookupResult.

       A  call  to TSHostLookup() may be synchronous—in which case the handler for contp will be called with the
       answer before the call to TSHostLookup() returns—or the call to  TSHostLookup()  may  be  asynchronous—in
       which  case  it  returns immediately with a TSAction, and the handler contp will be called in the future.
       See Actions for guidance.

       In particular, contp must have been created with a TSMutex; see TSContCreate()
