Subject: [PATCH 05/11] hashmap_get_next takes "const struct hashmap_entry *"
Date: Mon, 26 Aug 2019 02:43:26 +0000 [thread overview]
Message-ID: <20190826024332.3403-6-e@80x24.org> (raw)
In-Reply-To: <20190826024332.3403-1-e@80x24.org>
This is less error-prone than "const void *" as the compiler
now detects invalid types being passed.
Signed-off-by: Eric Wong <e@80x24.org>
