[PATCH v2 5/7] parse-options: add precision handling for OPTION_NEGBIT

From
René Scharfe <l.s.r@web.de>
Date
Jul 9, 2025, 09:45 UTC
Message-ID
<c492e2cd-d1aa-43ba-83c0-bd8f1a4d2f19@web.de>
In-Reply-To
<802eba72-c100-429a-80b7-7a0e8b6559ed@web.de>

Similar to 09705696f7 (parse-options: introduce precision handling for `OPTION_INTEGER`, 2025-04-17) support value variables of different sizes for OPTION_NEGBIT. Do that by requiring their "precision" to be set, casting their "value" pointer accordingly and checking whether the value fits.
