Subject: [PATCH 3/6] parse-options: add precision handling for OPTION_BIT
Date: Sun, 29 Jun 2025 13:50:52 +0200 [thread overview]
Message-ID: <7be6f365-7904-4086-992a-607d6c638d11@web.de> (raw)
In-Reply-To: <cf5cd57d-733f-4239-80f8-23bdc1523ab2@web.de>
Similar to 09705696f7 (parse-options: introduce precision handling for
`OPTION_INTEGER`, 2025-04-17) support value variables of different sizes
for OPTION_BIT. Do that by requiring their "precision" to be set,
casting their "value" pointer accordingly and checking whether the value
fits.
