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 timeout, 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.
