ares_timeout - return maximum time to wait

The ares_timeout(3) function determines the maximum time for which the caller should wait before invoking ares_process(3) to process timeouts. The parameter maxtv specifies a existing maximum timeout, or NULL if the caller does not wish to apply a maximum timeout. The parameter tv must point to a writable buffer of type structtimeval It is valid for maxtv and tv to have the same value. If no queries have timeouts pending sooner than the given maximum timeout, ares_timeout(3) returns the value of maxtv; otherwise ares_timeout(3) stores the appropriate timeout value into the buffer pointed to by tv and returns the value of tv.
