Subject: [PATCH 4/8] setup.c: introduce setup_adjust_path()
Date: Wed, 28 Mar 2018 19:55:33 +0200 [thread overview]
Message-ID: <20180328175537.17450-5-pclouds@gmail.com> (raw)
In-Reply-To: <20180328175537.17450-1-pclouds@gmail.com>
From: Duy Nguyen <pclouds@gmail.com>
When $CWD is moved, relative path must be updated to be relative to
the new $CWD. This function helps do that. The _in_place version is
just for convenient (and we will use it quite often in subsequent
patches).
