The branch stable/13 has been updated by emaste: URL: https://cgit.FreeBSD.org/src/commit/?id=c90c45ac725ba2a7f9bb940a1d555a025b7e47aa commit c90c45ac725ba2a7f9bb940a1d555a025b7e47aa Author: Ed Maste <emaste@FreeBSD.org> AuthorDate: 2023-10-13 20:25:53 +0000 Commit: Ed Maste <emaste@FreeBSD.org> CommitDate: 2023-10-16 17:52:57 +0000 ptsname.3: accommodate upcoming POSIX Issue 8 ptsname_r POSIX has accepted a proposal[1] to add glibc-compatible ptsname_r. It indicates an error by returning the error number, rather than returning -1 and setting errno. Update RETURN VALUES in ptsname_r's man page now to encourage folks to test that the return value != 0 rather than == -1.
