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.
