Subject: [PATCH v2 2/3] imap-send: be more careful when casting to `curl_off_t`
Date: Fri, 26 Sep 2025 10:32:51 +0000 [thread overview]
Message-ID: <fdd1327e7bbc0f42c11c354346859437eb29448b.1758882772.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1974.v2.git.1758882772.gitgitgadget@gmail.com>
From: Johannes Schindelin <johannes.schindelin@gmx•de>
When casting a `size_t` to `curl_off_t`, there is a currently uncommon
chance that the value can be cut off (`curl_off_t` is expected to be a
signed 64-bit data type).
