// In this API there are multiple functions which expect the caller to pass a pointer
// on return value as parameter.
// In order to make it clear if the caller should initialize the return value or not
// we have two flavor of types:
// - `GDExtensionXXXPtr` for pointer on an initialized value
// - `GDExtensionUninitializedXXXPtr` for pointer on uninitialized value
//
// Notes:
// - Not respecting those requirements can seems harmless, but will lead to unexpected
// segfault or memory leak (for instance with a specific compiler/OS, or when two
// native extensions start doing ptrcall on each other).
// - Initialization must be done with the function pointer returned by `variant_get_ptr_constructor`,
// zero-initializing the variable should not be considered a valid initialization method here !
// - Some types have no destructor (see `extension_api.json`'s `has_destructor` field), for
// them it is always safe to skip the constructor for the return value if you are in a hurry ;-)

* Each GDExtension should define a C function that matches the signature of GDExtensionInitializationFunction,

*
* For example:
*
* GDExtensionBool my_extension_init(GDExtensionInterfaceGetProcAddress p_get_proc_address, GDExtensionClassLibraryPtr p_library, GDExtensionInitialization *r_initialization);
*
* This function's name must be specified as the 'entry_symbol' in the .gdextension file.
*
* This makes it the entry point of the GDExtension and will be called on initialization.
*
* The GDExtension can then modify the r_initialization structure, setting the minimum initialization level,
* and providing pointers to functions that will be called at various stages of initialization/shutdown.
*
* The rest of the GDExtension's interface to Godot consists of function pointers that can be loaded
* by calling p_get_proc_address("...") with the name of the function.
*
* For example:
*
* GDExtensionInterfaceGetGodotVersion get_godot_version = (GDExtensionInterfaceGetGodotVersion)p_get_proc_address("get_godot_version");
*
* (Note that snippet may cause "cast between incompatible function types" on some compilers, you can
* silence this by adding an intermediary `void*` cast.)
*
* You can then call it like a normal function:
*
* GDExtensionGodotVersion godot_version;
* get_godot_version(&godot_version);
* printf("Godot v%d.%d.%d\n", godot_version.major, godot_version.minor, godot_version.patch);
