.TH ARES_TIMEOUT 3 "25 July 1998"
|
||
|
|
.SH NAME
|
||
|
|
ares_timeout \- return maximum time to wait
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <ares.h>
|
||
|
|
|
||
|
|
struct timeval *ares_timeout(ares_channel \fIchannel\fP,
|
||
|
|
struct timeval *\fImaxtv\fP,
|
||
|
|
struct timeval *\fItv\fP)
|
||

|
||
|
|
.SH DESCRIPTION
|
||
|
|
The \fBares_timeout(3)\fP function determines the maximum time for which the
|
||
|
|
caller should wait before invoking \fIares_process(3)\fP to process timeouts.
|
||
|
|
The parameter \fImaxtv\fP specifies a existing maximum timeout, or \fBNULL\fP
|
||
|
|
if the caller does not wish to apply a maximum timeout. The parameter
|
||
|
|
\fItv\fP must point to a writable buffer of type \fBstruct timeval\fP It is
|
||
|
|
valid for \fImaxtv\fP and \fItv\fP to have the same value.
|
||
|
|
|
||
|
|
If no queries have timeouts pending sooner than the given maximum timeout,
|
||
|
|
\fBares_timeout(3)\fP returns the value of \fImaxtv\fP; otherwise
|
||
|
|
\fBares_timeout(3)\fP stores the appropriate timeout value into the buffer
|
||
|
|
pointed to by \fItv\fP and returns the value of \fItv\fP.
