From e7f136bf93132c24183c168a9a054540e6216c06 Mon Sep 17 00:00:00 2001 From: Devin Lehmacher Date: Mon, 13 Mar 2017 16:43:54 -0400 Subject: [PATCH 1/1] path.c: add xdg_cache_home We already have xdg_config_home to format paths relative to XDG_CONFIG_HOME. Let's provide a similar function xdg_cache_home to do the same for paths relative to XDG_CACHE_HOME.
