struct type_name {
    int a;
}

int type_name(int a);

How can I get the function and type from importC? is there a auto rename mechanism ?

The most pragmatic workaround is to add a typedef to the C code:

int S;
struct S { int a, b; };
typedef struct S S_t;    // add this typedef

Thanks for tips.

This will not work for me. (huge code base I can not change and maintain)

You don't have to change the code where the type is defined per se, you just need to put it in any C file that can access the C symbol.

clib_helpers.c:

#include<hugelibrary.h>

typedef struct S S_t;

app.d:

import clib_helpers;

S_t s;

Thanks for the explain.

I will think about this.

my solution use ctfe symbol_name to get d define, and the symbol type name is get from ref place, (function arguments, struct field), so to fix it I need replace the type ref from headers files. In this case I get a wrong reflect type when I use __traits(getMember, module, symbol);
