.TH ARES_DUP 3 "26 May 2009"
|
|
.SH NAME
|
|
ares_dup \- Duplicate a resolver channel
|
|
.SH SYNOPSIS
|
|
.nf
|
|
.B #include <ares.h>
|
|
.PP
|
|
.B int ares_dup(ares_channel *\fIchannel\fP, ares_channel \fIsource\fP)
|
|
.fi
|
|
.SH DESCRIPTION
|
|
The \fBares_dup(3)\fP function duplicates an existing communications channel
|
|
for name service lookups. If it returns successfully, \fBares_dup(3)\fP will
|
|
set the variable pointed to by \fIchannel\fP to a handle used to identify the
|
|
name service channel. The caller should invoke \fIares_destroy(3)\fP on the
|
|
handle when the channel is no longer needed.
|
|
|
|
The \fBares_dup_options\fP function also initializes a name service channel,
|
|
with additional options set exactly as the \fIsource\fP channel has them
|
|
configured.
