      Node.js N-API napi_create_typedarray

      Node.js N-API napi_create_typedarray

      新增于: v8.0.0 N-API version: 1 napi_status napi_create_typedarray(napi_env env, napi_typedarray_type type, size_t length, napi_value arraybuffer, size_t byte_offset, napi_value* result) [in] env: The environment that the API is invoked under. [in] type: Scalar datatype of the elements within the TypedArray. [in] length: Number of elements in the TypedArray. [in] arraybuffer: ArrayBuffer underlying the typed array. [in] byte_offset: The byte offset within the ArrayBuffer from which to start projecting the TypedArray. [out] result: A napi_value representing a JavaScript TypedArray. Returns napi_ok if the API succeeded.

      This API creates a JavaScript TypedArray object over an existing ArrayBuffer. TypedArray objects provide an array-like view over an underlying data buffer where each element has the same underlying binary scalar datatype.

      It’s required that (length * size_of_element) + byte_offset should be <= the size in bytes of the array passed in. If not, a RangeError exception is raised.

      JavaScript TypedArray objects are described in Section 22.2 of the ECMAScript Language Specification.
