## Andere Middlewares

Es gibt viele andere ASGI-Middlewares.

Zum Beispiel:

            final int len = this.inputBuffer.encode(dst, dstIndex);
            SMBUtil.writeInt4(len, dst, inBufferLengthOffset);
            dstIndex += len;
        }
        return dstIndex - start;
    }

        // Compression count (2 bytes)

     * all but the first smb of the chaain do not have a header
     * and therefore we do not want to writeHeaderWireFormat. We
     * just recursivly call writeAndXWireFormat.
     */

    @Override

        System.arraycopy(this.fileId, 0, dst, dstIndex, 16);
        dstIndex += 16;

        for (final Smb2Lock l : this.locks) {
            dstIndex += l.encode(dst, dstIndex);
        }
        return dstIndex - start;
    }

    /**

    private long reserved;  // Must be zero

    }
    
    @Override
    public void encode(byte[] buffer, int offset) {

        writeInt4(buffer, offset, 16);  // Next
        writeInt2(buffer, offset + 4, nameLen);  // NameOffset
