Subject: [PATCH v4 3/6] wrapper: move is_empty_file() and rename it as is_empty_or_missing_file()
Date: Thu, 7 Jul 2016 01:55:20 +0530 [thread overview]
Message-ID: <20160706202523.9850-4-pranit.bauva@gmail.com> (raw)
In-Reply-To: <20160706202523.9850-1-pranit.bauva@gmail.com>
is_empty_file() can help to refactor a lot of code. This will be very
helpful in porting "git bisect" to C.
