com.sun.jna.Structure.FFIType
static class Structure.FFIType
This class auto-generates an ffi_type structure appropriate for a given structure for use by libffi. The lifecycle of this structure is easier to manage on the Java side than in native code.

IMPORTANT
When deriving from an existing Structure subclass, ensure that
you augment the list provided by the superclass, e.g.
protected List getFieldOrder() {
List fields = new ArrayList(super.getFieldOrder());
fields.addAll(Arrays.asList(new String[] { ... }));
return fields;
}
Field order must be explicitly indicated, since the
field order as returned by Class.getFields() is not
guaranteed to be predictable.
