From 78d6dcec6c49bd2fa830237a46fd14337bc9fd4c Mon Sep 17 00:00:00 2001 From: Anatol Pomozov Date: Thu, 23 Apr 2020 17:28:43 -0700 Subject: Add a utility function to check whether a file exists in the cache It is similar to _alpm_filecache_find() but does not return a dynamically allocated memory to user. Thus the user does not need to free this resource.
