From 3e015d815b3f28bfd874bf8a1697308ef9af2b4c Mon Sep 17 00:00:00 2001 From: Julia Suvorova Date: Thu, 1 Mar 2018 10:08:06 +0300 Subject: use g_path_get_basename instead of basename basename(3) and dirname(3) modify their argument and may return pointers to statically allocated memory which may be overwritten by subsequent calls. g_path_get_basename and g_path_get_dirname have no such issues, and therefore more preferable.
