[zerolib] Pinvoke and functions with Variable Arguments

[ghost]

The keyword params doesn't work. What should I do?

@lucabol How would you handle functions like printf in your LibC stub?

[MichalStrehovsky]

params is not equivalent to vararg. You'd need to use the undocumented __arglist keyword. But that one doesn't work with native AOT in general.

You can just declare a p/invoke for each signature shape you need:

[DllImport(...)]
int printf(byte* format, int intArg1);

[DllImport(...)]
int printf(byte* format, int intArg1, int intarg2);

[DllImport(...)]
int printf(byte* format, int intArg, int intArg2, int intarg3);
