ARES_TIMEOUT(3)						       ARES_TIMEOUT(3)

NAME
       ares_timeout - return maximum time to wait

SYNOPSIS
       #include <ares.h>

       struct timeval *ares_timeout(ares_channel channel,
       struct timeval *maxtv, struct timeval *tv)

DESCRIPTION
       The  ares_timeout  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 struct timeval.  It is valid
       for maxtv and tv to have the same value.

       If no queries have timeouts pending sooner than the given maximum time‐
       out,  ares_timeout  returns  the value of maxtv; otherwise ares_timeout
       stores the appropriate timeout value into the buffer pointed to	by  tv
       and returns the value of tv.
