Modify dns_get_record to test for query result based on dns_errno to accommodate modern FreeBSD, for which res_nsearch() does not update h_errno directly. Add new php_dns_errno function, and have it consult statp->res_h_errno when OS has res_nsearch(). Fixes #81618

might be better if you branch from |
Good catch about macro - edited.
Oops, you're right.. I see the git workflow now. Let me see about correcting that. |

I'll rebase, then shift the PR base... |

Nevermind. I'll submit a PR for a commit off the 7.3 branch. |

Modify dns_get_record to test for query result based on dns_errno to
accommodate modern FreeBSD, for which res_nsearch() does not update
h_errno directly. Add new php_dns_errno macro, and have it consult

Fixes #81618
This approach is more complete than #7650, because it deals with the
general case for any subsequent or future calls to php_dns_errno().
Test borrowed from #7650.
Will need to be backported to 8.1, 7.3 and 7.4 branches.
