Subject: [dev] Improper code in CAReceiveMessage function ?
Hi,
I was just going through the iotivity source code in caipserver.c file. I have
doubt regarding
possibility of improper code.
In the following code in CAReceiveMessage function:
if (flags & CA_IPV6)
{
namelen = sizeof (struct sockaddr_in6);
level = IPPROTO_IPV6;
type = IPV6_PKTINFO;
len = sizeof (struct in6_pktinfo);
}
else
{
namelen = sizeof (struct sockaddr_in);
level = IPPROTO_IP;
type = IP_PKTINFO;
len = sizeof (struct in6_pktinfo);
}
May I know why the len is set to sizeof (struct in6_pktinfo) in case of IPv4
packet? Is it intentional with a purpose?
Shouldn't it be set to sizeof (struct in_pktinfo) ? It will be helpful if
someone can clear my doubt.
Thanks & Regards,
