pcap_open_offline, pcap_fopen_offline - open a saved capture file for reading
pcap_t *pcap_open_offline(const char *fname, char *errbuf);
pcap_t *pcap_fopen_offline(FILE *fp, char *errbuf);
pcap_open_offline() is called to open a ``savefile'' for reading.
fname specifies the name of the file to open. The file can have the pcap file format as described in pcap-savefile(5), which is the file
format used by, among other programs, tcpdump(8) and tcpslice(1), or can have the pcap-ng file format, although not all pcap-ng files can
be read. The name "-" in a synonym for stdin.
Alternatively, you may call pcap_fopen_offline() to read dumped data from an existing open stream fp. Note that on Windows, that stream
should be opened in binary mode.
pcap_open_offline() and pcap_fopen_offline() return a pcap_t * on success and NULL on failure. If NULL is returned, errbuf is filled in
with an appropriate error message. errbuf is assumed to be able to hold at least PCAP_ERRBUF_SIZE chars.

I want to write a small application using Libpcap in C on Linux.
Currently, it starts to sniff and waits for the packets. But that's not what I need actually. I want it to wait for N seconds and then stop listening. (I think there's something wrong with my usage of 'pcap_open_live'...)
