From 3afffc2a59cfc3888a84b2b2305b5312393ff4e8 Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Wed, 6 Nov 2019 10:44:26 +0100 Subject: Remove raw file descriptors from unpack write paths Instead, use stdio FILE pointers. On POSIX systems, use fileno to get the file descriptor and hopefully create sparase files.
