- .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.
- .SH SEE ALSO
