This forces communications +to go over a certain interface, which can be useful on multi-homed machines. +This option is only supported on Linux, and root privileges are required +for the option to work. If SO_BINDTODEVICE is not supported or the +setsocktop call fails (probably because of permissions), the error is +silently ignored. +.SH SEE ALSO +.BR ares_set_local_ipv4 (3) +.BR ares_set_local_ipv6 (3) +.SH NOTES +This function was added in c-ares 1.7.4 +.SH AUTHOR +Ben Greear -- cgit v1.2.3
