* stub out more types/funcs to compile against golang.org/x/net/internal/socket These are changes need to compile github.com/domainr/dnsr/ with TinyGo. See issue tinygo-org/net#14. These change are mostly to fix missing symbols in src/net. Missing types and functions are cut-and-pasted from go1.21.4. Functions are stubbed out returning errors.New("not implemented"). DNRS is compiled by running tinygo test: sfeldma@nuc:~/work/dnsr$ tinygo test -target=wasi With this patch, and a corresponding patch for tinygo/ to fixup crypto/tls, you should get a clean compile.
