Todo esto podría parecer complicado. Y puede que no esté muy claro cómo es útil aún.

Estos ejemplos son intencionalmente simples, pero muestran cómo funciona todo.

        byte[] buf = new byte[bodyLen];
        int pos = 0;

        // structureSize (LE) - includes 1 byte of the variable part
        SMBUtil.writeInt2(49, buf, pos);
        pos += 2;
        // 2 reserved bytes
        pos += 2;
        // ctlCode
        SMBUtil.writeInt4(ctlCode, buf, pos);
        pos += 4;
        // fileId (16 bytes)
        byte[] fid = fileId != null ? fileId : new byte[16];

        buf[idx++] = 0; // totalParameterCount high byte -> value 5
        buf[idx++] = 3; // totalDataCount low
        buf[idx++] = 0; // totalDataCount high
        idx += 2; // 2-byte reserved field (not 4 as the code shows)
        buf[6] = 2; // parameterCount low
        buf[7] = 0; // high
        buf[8] = 4; // parameterOffset low
        buf[9] = 0; // high

    private static byte[] buildExportName(Oid mech, String name) throws GSSException {
        byte[] der = mech.getDER();
        byte[] nb = name.getBytes();
        int len = 2 + 2 + der.length + 4 + nb.length;
        byte[] out = new byte[len];
        int i = 0;
        out[i++] = 0x04; // TOK_ID[0]
        out[i++] = 0x01; // TOK_ID[1]
        out[i++] = (byte) ((der.length >> 8) & 0xFF);

... et passera ce que cela renvoie comme valeur de la dépendance à notre *fonction de chemin d'accès*, en tant que paramètre `fixed_content_included` :

Tout cela peut sembler artificiel. Et il n’est peut‑être pas encore très clair en quoi c’est utile.

Ces exemples sont volontairement simples, mais ils montrent comment tout cela fonctionne.

├── DurableHandleRequest.java        - Durable handle v1 support
├── DurableHandleV2Request.java      - Durable handle v2 with timeout
└── HandleReconnector.java           - Automatic handle reconnection
```

#### 2.2 Implementation Tasks
- [ ] Implement persistent/durable handle contexts
- [ ] Add handle GUID generation and tracking
- [ ] Implement handle state serialization
- [ ] Create reconnection logic with handle replay

        assertEquals("ABCD", new String(dst2));

        // Test with offset
        char[] dst3 = new char[10];
        java.util.Arrays.fill(dst3, 'X');
        Hexdump.toHexChars(0xFF, dst3, 2, 2);
        assertEquals("XXFFXXXXXX", new String(dst3));

        // Test long conversion

        Hexdump.toHexChars(0x123456789ABCDEF0L, dst4, 0, 16);

위의 코드 예제에서는 직접 사용하지 않고, FastAPI에 전달하여 FastAPI가 이를 사용하도록 합니다.

`FastAPI` 앱의 `lifespan` 매개변수는 **비동기 컨텍스트 매니저**를 받으므로, 새 `lifespan` 비동기 컨텍스트 매니저를 전달할 수 있습니다.
