16 .TH ARES_DUP 3 "26 May 2009"
18 ares_dup \- Duplicate a resolver channel
23 .B int ares_dup(ares_channel *\fIdest\fP, ares_channel \fIsource\fP)
26 The \fBares_dup(3)\fP function duplicates an existing communications channel
27 for name service lookups. If it returns successfully, \fBares_dup(3)\fP will
28 set the variable pointed to by \fIdest\fP to a handle used to identify the
29 name service channel. The caller should invoke \fIares_destroy(3)\fP on the
30 handle when the channel is no longer needed.
32 The \fBares_dup_options\fP function also initializes a name service channel,
33 with additional options set exactly as the \fIsource\fP channel has them
38 .BR ares_library_init(3)
40 ares_dup(3) was added in c-ares 1.6.0
