Subject: Some platforms actually have an unsigned msghdr.msg_iovlen even
X-Git-Tag: dnsdist-1.6.0-alpha1~38^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=refs%2Fpull%2F9979%2Fhead;p=thirdparty%2Fpdns.git

Some platforms actually have an unsigned msghdr.msg_iovlen even
though Posix says it should be an int.

So use the power of C++ to make the var the same type as msghdr.msg_iovlen.
