ARES_TIMEOUT(3) Introduction to Library Functions 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.
