编写PCAP捕获文件头需要按照PCAP文件格式的规范进行操作。下面是一个完善且全面的答案: PCAP捕获文件头的数据结构如下: 代码语言:c 复制 typedef struct pcap_hdr_s { guint32 magic_number; /* 0xa1b2c3d4 */ guint16 version_major; /* 主版本号 */ guint16 version_minor; /* 次版本号 */ gint32...
2、数据包,由数据包头和数据构成,其中数据包头为可变长度,基本分3种结构(struct pcaprec_hdr、struct pcaprec_modified_hdr或者 truct pcaprec_ss990915_hdr)。常用数据包头结构体 struct pcaprec_hdr ,另外2种是在struct pcaprec_hdr扩展出来,其中 ts_sec 为报文的秒、ts_usec为报文微秒,incl_len 为报文捕获长...
