rra-c-util 3.2

Nothing particularly exciting in this release, but since I'm releasing a new version of one of its client projects, I may as well kick out the accumulated fixes.

The strndup replacement now checks whether it was called on NULL and returns NULL with errno set in that case, thanks to Carsten Hey. And the network utility library now properly zeroes sockaddr_in and sockaddr_in6 structs in all cases, just in case stray non-zeroed data may cause problems, thanks to Bo Lindbergh.

You can get the latest version from the rra-c-util distribution page.
