/**
* The `process.dlopen()` method allows dynamically loading shared objects. It is primarily used by `require()` to load C++ Addons, and
* should not be used directly, except in special cases. In other words, `require()` should be preferred over `process.dlopen()`
* unless there are specific reasons such as custom dlopen flags or loading from ES modules.
*
* The `flags` argument is an integer that allows to specify dlopen behavior. See the `[os.constants.dlopen](https://nodejs.org/docs/latest-v20.x/api/os.html#dlopen-constants)`
* documentation for details.
*
* An important requirement when calling `process.dlopen()` is that the `module` instance must be passed. Functions exported by the C++ Addon
* are then accessible via `module.exports`.
*
* The example below shows how to load a C++ Addon, named `local.node`, that exports a `foo` function. All the symbols are loaded before the call returns, by passing the `RTLD_NOW` constant.
* In this example the constant is assumed to be available.
*
* ```js
* import { dlopen } from 'node:process';
* import { constants } from 'node:os';
* import { fileURLToPath } from 'node:url';
*
* const module = { exports: {} };
* dlopen(module, fileURLToPath(new URL('local.node', import.meta.url)),
* constants.dlopen.RTLD_NOW);
* module.exports.foo();
* ```
* @since v0.1.16

/**
* The `process.emitWarning()` method can be used to emit custom or application
