Subject: [PATCH v2 02/11] bisect--helper: introduce new `write_in_file()` function
Date: Sat, 21 Mar 2020 17:10:11 +0100	[thread overview]
Message-ID: <20200321161020.22817-3-mirucam@gmail.com> (raw)
In-Reply-To: <20200321161020.22817-1-mirucam@gmail.com>

Let's refactor code adding a new `write_in_file()` function
that opens a file for writing a message and closes it.

This helper will be used in later steps and makes the code
simpler and easier to understand.
