Implicit Forward Declared Struct incorrectly Converted #275

Open miguelmartin75 opened 11 months ago

miguelmartin75 commented 11 months ago

For example:

foo.h:

typedef struct FooImpl* Foo;

Should output

discard "forward decl of FooImpl"
type Foo* = ptr FooImpl

However, instead c2nim outputs:

type Foo* = ptr FooImpl

If you attempt to import foo, Nim will complain about FooImpl not being declared.

One can get around this via forward declaring on a separate line in the header file, i.e. the C header should look as follows:

struct FooImpl;
typedef struct FooImpl* Foo;

Never mind, in both cases, this does not work. I'm not sure how to deal with private/Opaque structs.

Apologies for the noise.
