/**
 * This function get the priority of the current process.
 * On Unix, it uses the [`getpriority(2)`](https://linux.die.net/man/2/getpriority).
 *
 * On Windows, it uses the [`GetThreadPriority`](https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-getthreadpriority) function.

 * | Priority Constant                  | Value     | Description                                                                                                                                                                                                                       |
 * |------------------------------------|-----------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
 * | THREAD_MODE_BACKGROUND_BEGIN       | 0x00010000| Begin background processing mode. The system lowers the resource scheduling priorities of the thread so that it can perform background work without significantly affecting activity in the foreground.                              |
 * |                                    |           | This value can be specified only if hThread is a handle to the current thread. The function fails if the thread is already in background processing mode.                                                                           |

 * | THREAD_MODE_BACKGROUND_END         | 0x00020000| End background processing mode. The system restores the resource scheduling priorities of the thread as they were before the thread entered background processing mode.                                                            |
 * |                                    |           | This value can be specified only if hThread is a handle to the current thread. The function fails if the thread is not in background processing mode.                                                                               |
