Defaults with the same ABI layout are generated for most platform-defined types. These can either by bitcasted to, or overridden by defining them in the project root: Defaults with the same ABI layout are generated for most platform-defined types. These can either by bitcasted to, or overridden by defining them in the project root:
```zig ```zig
pub const xcb_connection_t = if (@hasDecl(root, "xcb_connection_t")) root.xcb_connection_t else @Type(.Opaque); pub const xcb_connection_t = if (@hasDecl(root, "xcb_connection_t")) root.xcb_connection_t else opaque{};
``` ```
For some times (such as those from Google Games Platform) no default is known. Usage of these without providing a concrete type in the project root generates a compile error. For some times (such as those from Google Games Platform) no default is known, but an `opaque{}` will be used by default. Usage of these without providing a concrete type in the project root is likely an error.
