<details> <summary> About stdlib... </summary> <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p> <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p> <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p> <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p> </details> # Equal Typed Array Types [![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]  > Assert that two Node-API typed array data types are equal.  <section class="intro"> </section>   <section class="installation"> ## Installation ```bash npm install @stdlib/assert-napi-equal-typedarray-types ``` </section> <section class="usage"> ## Usage ```javascript var headerDir = require( '@stdlib/assert-napi-equal-typedarray-types' ); ``` #### headerDir Absolute file path for the directory containing header files for C APIs. ```javascript var dir = headerDir; // returns <string> ``` </section>   <section class="notes"> </section>   <section class="examples"> ## Examples ```javascript var headerDir = require( '@stdlib/assert-napi-equal-typedarray-types' ); console.log( headerDir ); // => <string> ``` </section>   * * * <section class="c"> ## C APIs  <section class="intro"> </section>   <section class="usage"> ### Usage ```c #include "stdlib/assert/napi/equal_typedarray_types.h" ``` #### stdlib_assert_napi_equal_types( env, type1, type2, \*message, \*err ) Asserts that two Node-API typed array data types are equal. ```c #include <node_api.h> static napi_value addon( napi_env env, napi_callback_info info ) { napi_typedarray_type vtype1; napi_typedarray_type vtype2; // ... napi_value err; napi_status status = stdlib_assert_napi_equal_typedarray_types( env, vtype1, vtype2, "Must have equal types.", &err ); assert( status == napi_ok ); if ( err != NULL ) { assert( napi_throw( env, err ) == napi_ok ); return NULL; } // ... } ``` The function accepts the following arguments: - **env**: `[in] napi_env` environment under which the function is invoked. - **type1**: `[in] napi_valuetype` first data type. - **type2**: `[in] napi_valuetype` second data type. - **message**: `[in] char*` error message. - **err**: `[out] napi_value*` pointer for storing a JavaScript error. ```c napi_status stdlib_assert_napi_equal_typedarray_types( const napi_env env, const napi_typedarray_type type1, const napi_typedarray_type type2, const char *message, napi_value *err ); ``` The function returns a `napi_status` status code indicating success or failure (returns `napi_ok` if success). </section>   <section class="notes"> ### Notes - If provided unequal data types, the function sets `err` with a JavaScript error; otherwise, `err` is set to `NULL`. </section>   <section class="examples"> </section>  </section>   <section class="references"> </section>   <section class="related"> </section>   <section class="main-repo" > * * * ## Notice This package is part of [stdlib][stdlib], a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
