16 .TH ARES_TIMEOUT 3 "25 July 1998"
18 ares_timeout \- return maximum time to wait
23 struct timeval *ares_timeout(ares_channel \fIchannel\fP,
24 struct timeval *\fImaxtv\fP,
25 struct timeval *\fItv\fP)
28 The \fBares_timeout(3)\fP function determines the maximum time for which the
29 caller should wait before invoking \fIares_process(3)\fP to process timeouts.
30 The parameter \fImaxtv\fP specifies a existing maximum timeout, or \fBNULL\fP
31 if the caller does not wish to apply a maximum timeout. The parameter
32 \fItv\fP must point to a writable buffer of type \fBstruct timeval\fP It is
33 valid for \fImaxtv\fP and \fItv\fP to have the same value.
35 If no queries have timeouts pending sooner than the given maximum timeout,
36 \fBares_timeout(3)\fP returns the value of \fImaxtv\fP; otherwise
37 \fBares_timeout(3)\fP stores the appropriate timeout value into the buffer
38 pointed to by \fItv\fP and returns the value of \fItv\fP.
