"Montar" significa añadir una aplicación completamente "independiente" en un path específico, que luego se encarga de manejar todo bajo ese path, con las _path operations_ declaradas en esa sub-aplicación.

### Aplicación de nivel superior { #top-level-application }

Primero, crea la aplicación principal de nivel superior de **FastAPI**, y sus *path operations*:

{* ../../docs_src/sub_applications/tutorial001_py39.py hl[3, 6:8] *}

     *
     * @return the ttl
     */
    public final int getTtl() {
        return this.ttl;
    }

    /**
     * Gets the referral path.
     *
     * @return the rpath
     */
    public final String getRpath() {

     * Gets the node name for this referral.

     */

"Mounting" means adding a completely "independent" application in a specific path, that then takes care of handling everything under that path, with the _path operations_ declared in that sub-application.

### Top-level application { #top-level-application }

First, create the main, top-level, **FastAPI** application, and its *path operations*:

{* ../../docs_src/sub_applications/tutorial001_py39.py hl[3, 6:8] *}

func IsLikelyMountPoint(path string) bool {

	if v, ok := mountPointCache.Load(path); ok {

	}
	wpath, _ := windows.UTF16PtrFromString(path)
	wvolume := make([]uint16, len(path)+1)

	if err := windows.GetVolumePathName(wpath, &wvolume[0], uint32(len(wvolume))); err != nil {
		mountPointCache.Store(path, false)
		return false

                // restores almost everything that was modified, except the path.
                rpath.setPath(savedPath);
