Subject: Rename nlmsg_for_each_msg() to nlmsg_for_each()
X-Git-Tag: libnl3_0~20
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9513d4ce34a9e2c78645eabe35f564facfc1db1f;p=thirdparty%2Flibnl.git

Rename nlmsg_for_each_msg() to nlmsg_for_each()

Also put remaining variable on local stack instead of requiring the user
to supply it. Old interface is kept for compatibility.
