    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>

### Usage

```c
#include "stdlib/napi/create_uint32.h"
```

#### stdlib_napi_create_uint32( env, value, \*out )

Converts an unsigned 32-bit integer to a Node-API value.

```c
#include "stdlib/napi/create_uint32.h"
#include <node_api.h>

static napi_value addon( napi_env env, napi_callback_info info ) {

    // ...

    napi_value value;
    napi_status status = stdlib_napi_create_uint32( env, 1, &value );
    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.
-   **value**: `[in] uint32_t` unsigned 32-bit integer.
-   **out**: `[out] napi_value*` destination for storing output value.

```c
napi_status stdlib_napi_create_uint32( const napi_env env, const uint32_t value, napi_value *out );
```

The function returns a `napi_status` status code indicating success or failure (returns `napi_ok` if success).

#### STDLIB_NAPI_CREATE_UINT32( env, expression, name )

Macro for converting an unsigned 32-bit integer to a Node-API value.

```c
#include "stdlib/napi/create_uint32.h"
#include "stdlib/napi/argv_uint32.h"
#include "stdlib/napi/argv.h"
#include <node_api.h>
#include <stdint.h>

static uint32_t fcn( const uint32_t v ) {
    return v;
}

// ...

static napi_value addon( napi_env env, napi_callback_info info ) {
    // Retrieve add-on callback arguments:
    STDLIB_NAPI_ARGV( env, info, argv, argc, 1 );

    // Convert the first argument to a C type:
    STDLIB_NAPI_ARGV_UINT32( env, value, argv, 0 );

    // ...

    // Convert a value having a C type to a Node-API value:
    STDLIB_NAPI_CREATE_UINT32( env, fcn( value ), out );

    return out;
}
```

The macro expects the following arguments:

-   **env**: environment under which the callback is invoked.
-   **expression**: expression returning an unsigned 32-bit integer.
-   **name**: output variable name.
