Defines and flags

[Aurel300]

(heavily inspired by libuv/asys work of course)

It should be possible to easily declare constants which would normally be accessible in C by including the headers of the library. A specialisation for "flags" fields, i.e. integer constants meant to combined with bitwise-OR would be useful.

Something like:

class Foobar extends ammer.Library<"foobar"> {
  @:ammer.native("FOOBAR_EXAMPLE") public static var example:Int;
  @:ammer.native("FOOBAR_ELPMAXE") public static var elpmaxe:Int;
}

Should create a glue method in the C stubs that will be called during static initialisation. The method will simply return an array of the required values.

int *glue_foobar_ints(void) {
  return {
    FOOBAR_EXAMPLE,
    FOOBAR_ELPMAXE
  };
}

And then:

class Foobar_Impl {
  static function __init__():Void {
    var ints = glue_foobar_ints();
    Foobar.example = ints[0];
    Foobar.elpmaxe = ints[1];
  }
}
