ARES_TIMEOUT(3)        FreeBSD Library Functions Manual        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(3) function determines the maximum time for which the
       caller should wait before invoking _process&section=3">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(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.
