bgpdump/debian/patches/clarify-pointer-cast.patch

Description: Clarify pointer usage
Author: Christoph Biedl <debian.axhn@manchmal.in-ulm.de>
Bug: https://bitbucket.org/ripencc/bgpdump/issues/30/
Last-Update: 2016-07-19

    The read_asn function handles pointer to as_t and u_int16_t as well,
    behaviour is controlled by the third parameter.

    Type-cast parameter 2 to avoid incompatible-pointer-types warnings
    from gcc.
