napi_detach_arraybuffer

napi_status napi_detach_arraybuffer(napi_env env,
                                    napi_value arraybuffer) 拷贝

• [in] env：调用 API 的环境。

  ¥[in] env: The environment that the API is invoked under.

• [in] arraybuffer：要分离的 JavaScript ArrayBuffer。

  ¥[in] arraybuffer: The JavaScript ArrayBuffer to be detached.

如果 API 成功，则返回 napi_ok。如果传入不可分离的 ArrayBuffer，则返回 napi_detachable_arraybuffer_expected。

¥Returns napi_ok if the API succeeded. If a non-detachable ArrayBuffer is passed in it returns napi_detachable_arraybuffer_expected.

通常，ArrayBuffer 是不可拆卸的，如果它之前已经拆卸过。引擎可能会对 ArrayBuffer 是否可拆卸施加附加条件。例如，V8 要求 ArrayBuffer 是外部的，即用 napi_create_external_arraybuffer 创建的。

¥Generally, an ArrayBuffer is non-detachable if it has been detached before. The engine may impose additional conditions on whether an ArrayBuffer is detachable. For example, V8 requires that the ArrayBuffer be external, that is, created with napi_create_external_arraybuffer.

此 API 表示调用 ArrayBuffer 分离操作，如 ECMAScript 语言规范的 第 24.1.1.3 节 中所定义。

¥This API represents the invocation of the ArrayBuffer detach operation as defined in Section 24.1.1.3 of the ECMAScript Language Specification.
