Subject: Make iter for DECLARE_TYPED_DIGESTMAP_FNS be a pointer.
X-Git-Tag: tor-0.2.6.1-alpha~163
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a14c6cb70f56c24cc76023366f8ae56900f72296;p=thirdparty%2Ftor.git

Make iter for DECLARE_TYPED_DIGESTMAP_FNS be a pointer.

This fixes a clangalyzer warning, and makes our C slightly better C.
