Nested Struct

Anonymous Nested Struct

Anonymous nested structs/unions are converted to inline Go struct types within the parent struct.

struct outer {
    struct {
        int x;
        int y;
    } inner;
};

type Outer struct {
    Inner struct {
        X c.Int
        Y c.Int
    }
}

Named Nested Struct

Named nested structs in C are accessible in the global scope, not just as anonymous nested types. llcppg handles this by creating separate type declarations for both the outer and inner structs.

Reason: In C, named nested structs are declared in the global scope and can be used independently. This means struct inner_struct can be used anywhere in the code, not just within the context of the outer struct.

typedef struct struct2 {
    char *b;
    struct inner_struct {
        long l;
    } init;
} struct2;

// This is valid C - inner_struct is in global scope
struct inner_struct inner = {123};

Generated Go code:

type InnerStruct struct {
    L c.Long
}

type Struct2 struct {
    B    *c.Char
    Init InnerStruct
}

This is equivalent to:

struct inner_struct {
    long l;
};
struct struct2 {
    char *b;
    struct inner_struct init;
};
