    • [in] env: The environment that the API is invoked under.
    • [out] result: The highest version of N-API supported.

    Returns napi_ok if the API succeeded.

    This API returns the highest N-API version supported by the Node.js runtime. N-API is planned to be additive such that newer releases of Node.js may support additional API functions. In order to allow an addon to use a newer function when running with versions of Node.js that support it, while providing fallback behavior when running with Node.js versions that don’t support it:

    • Call napi_get_version() to determine if the API is available.
    • If available, dynamically load a pointer to the function using uv_dlsym().
    • Use the dynamically loaded pointer to invoke the function.
    • If the function is not available, provide an alternate implementation that does not use the function.
