The branch stable/14 has been updated by karels: URL: https://cgit.FreeBSD.org/src/commit/?id=e9e63d77c6b5ecd26c78502734cbc0fe85364685 commit e9e63d77c6b5ecd26c78502734cbc0fe85364685 Author: Mike Karels <karels@FreeBSD.org> AuthorDate: 2024-01-27 15:40:07 +0000 Commit: Mike Karels <karels@FreeBSD.org> CommitDate: 2024-01-30 20:10:30 +0000 inet(3): clarify syntax accepted by inet_pton The section INTERNET ADDRESSES describes the acceptance of dotted values with varying number of parts in multiple bases. This applies to inet_aton and inet_addr, but not to inet_pton. Clarify this section by listing the functions to which this applies. Move the description of what inet_pton accepts into this section from STANDARDS, where it is easily missed. Rename the section to clarify that it applies only to IPv4. (inet_pton also works with IPv6.)
