ares_timeout(3) Library Functions Manual ares_timeout(3)
NAME
ares_timeout - return maximum time to wait
SYNOPSIS
#include <ares.h>
struct timeval *ares_timeout(const ares_channel_t *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 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.
