#### Description

Get information about the operating system.

On Linux this comes from the `/etc/os-release` file. On other systems, it may come from a variety of sources. You can either use the standard key names like `G_OS_INFO_KEY_NAME` or pass any UTF-8 string key name. For example, `/etc/os-release` provides a number of other less commonly used values that may be useful. No key is guaranteed to be provided, so the caller should always check if the result is `NULL`.
