Stel dat je Python installeert en het komt terecht in de map `/opt/custompython/bin`.

Als je kiest om de `PATH` omgevingsvariabele bij te werken, zal het installatieprogramma `/opt/custompython/bin` toevoegen aan de `PATH` omgevingsvariabele.

Dit zou er zo uit kunnen zien:

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/custompython/bin
```

const ODirectPlatform = true

// OpenFileDirectIO - bypass kernel cache.
func OpenFileDirectIO(filePath string, flag int, perm os.FileMode) (*os.File, error) {
	return directio.OpenFile(filePath, flag, perm)
}

// DisableDirectIO - disables directio mode.
