UUID和网络上的字节交换

是否有一种标准的、可接受的方式来通过网络(或文件存储)传输字节交换UUID?(我希望发送/存储16个原始字节,而不是将UUID转换为字符串表示形式。)

起初我认为应该将UUID划分为4个32位整数,并对每个整数调用htonl,但这听起来不太对劲。UUID具有内部结构(来自RFC 4122):

typedef struct {
    unsigned32  time_low;
    unsigned16  time_mid;
    unsigned16  time_hi_and_version;
    unsigned8   clock_seq_hi_and_reserved;
    unsigned8   clock_seq_low;
    byte        node[6];
} uuid_t;

这样做是否正确:

...
uuid.time_low = htonl( uuid.time_low );
uuid.time_mid = htons( uuid.time_mid );
uuid.time_hi_and_version = htons( uuid.time_high_and_version );
/* other fields are represented as bytes and shouldn't be swapped */
....

在写之前,然后相应的ntoh…在另一端阅读后调用?

谢谢
