From 11510decd020c3cb8936432d4d4bfb214492fcc4 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Sat, 15 Jun 2019 12:06:59 +0200 Subject: [PATCH] t/helper: add test-oidmap.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This new helper is very similar to "test-hashmap.c" and will help test how `struct oidmap` from oidmap.{c,h} can be used.
