If by "defer to the current style" you mean either 1) "the program using pcap_dispatch() could fall back to the current style" or 2) "libpcap could provide an API for interrupting pcap_dispatch() on a given pcap_t that, on Linux, uses an eventfd if eventfds are available and uses...

首先,它的效率不高,因为它虽然隐藏了回调模式但是仍然依赖于 pcap_dispatch()。其次,它不能检测EOF(译者注:end of file,意思是文件结束标志),所以当我们从一个文件中收集包的时候不是很有用(译者注:winpcap可以把捕获的数据包以很高的效率存在文件中,留待以后分析,这一点以后的课程中也会讲到)。

比如它效率很低,尽管隐藏了回调的方式,但它仍然依赖于函数pcap_dispatch();另外,它不能检测到EOF这个状态,那么如果数据包是从文件中读取过来的,那么它就不那么好用了。显然,pcap_next_ex()函数在此基础上做出了一些改进。最后我们来看一下pcap_next_ex()函数的返回值,引用文档中的描述:...
