// 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 ;-)
