I work with any third party code written with glic, and I need compile and run it in a musl runtime.

The code use `res_ninit`, but I cloud not find it in musl's resolv.h file.

I noticed that glibc use `res_ninit`, `res_nclose`, `res_nquery`, etc, and marked `res_init`, `res_query`, etc as deprecated, but musl still using the old signature.

I'm wondering:

- How do I compile the code that use the `res_ninit` routine signature?

- Is there a standard for the sinature for `resolv.h` (/usr/include/resolv.h)?

- Will musl will use the new `res_ninit` glibc current using or the `res_init` style still?
