.\" .\" Copyright 2010 by Ben Greear <greearb@candelatech.com> .\" SPDX-License-Identifier: MIT .\" .TH ARES_SET_LOCAL_DEV 3 "23 September 2024" .SH NAME ares_set_local_dev \- Bind to a specific network device when creating sockets. .SH SYNOPSIS .nf #include <ares.h> void ares_set_local_dev(ares_channel_t *\fIchannel\fP, const char* \fIlocal_dev_name\fP) .fi .SH DESCRIPTION The \fBares_set_local_dev\fP function causes all future sockets to be bound to this device with SO_BINDTODEVICE. This forces communications to go over a certain interface, which can be useful on multi-homed machines. This option is only supported on Linux, the interface must not be already bound to the socket or the current effective user must have CAP_NET_RAW capability in the current network namespace for the option to work. If SO_BINDTODEVICE is not supported or the setsockopt call fails (probably because of permissions), the error is silently ignored. .SH SEE ALSO .BR ares_set_local_ip4 (3) .BR ares_set_local_ip6 (3) .BR network_namespaces (7) .SH NOTES This function was added in c-ares 1.7.4
