ARES_TIMEOUT(3)

NAME
ares_fds - Get file descriptors to select on for name service

SYNOPSIS
#include <ares.h>

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

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 tvbuf must point to a writable buffer of type struct timeval. It is valid for maxtv and tvbuf 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 tvbuf and returns the value of tvbuf.
