From ff65d24ec4cac038e07a16692c3ae64d6e5fbc3c Mon Sep 17 00:00:00 2001 From: Neels Hofmeyr Date: Tue, 19 Nov 2019 00:21:14 +0100 Subject: utils_test: add osmo_print_n_test() A couple of times recently I've needed to copy out a substring to a buffer with limited size. Use of strncpy() or osmo_strlcpy() are nontrivial here. I wanted to have a dedicated function. After I wrote that function with a test, I noticed that I had already implemented the same thing a while ago, as osmo_print_n() :P So here is just the test.
