From 0741241c6b80bfd58417e95de984d60c9e9ef2a0 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 17 Jul 2009 10:13:21 -0700 Subject: connector: make callback argument type explicit The connector documentation states that the argument to the callback function is always a pointer to a struct cn_msg, but rather than encode it in the API itself, it uses a void pointer everywhere. This doesn't make much sense to encode the pointer in documentation as it prevents proper C type checking from occurring and can easily allow people to use the wrong pointer type. So convert the argument type to an explicit struct cn_msg pointer. Signed-off-by: Mike Frysinger Signed-off-by: David S.
