Because code that passes a pointer to a pointer to a pcap_t, rather than a
pointer to a pcap_t, to pcap_close() is erroneous code.
You cannot arrange that libpcap somehow make a pcap_t or a pointer to it
detectably invalid when you close the handle; if you want to know whether a
pcap_t has been closed, you will have to make your code explicitly mark it as
such. For example, replace all occurrences of
pcap_close(handle);
in your code with
pcap_close(handle);
handle = NULL;
