This patch changes the signatures of some functions to allow const pointers in places where a const qualified pointer is enough access for what the function does (e.g. nla_get_u8). It also changes some functions that take a pointer parameter and return a pointer derived from it to use the strchr idiom. This is not exhaustive in terms of places where const can be added, but it's a decent chunk that should not make the external api any more restrictive. http://lists.infradead.org/pipermail/libnl/2015-February/001826.html Signed-off-by: Rohan Joyce <rojoyce.github@gmail.com> Signed-off-by: Thomas Haller <thaller@redhat.com>
