PCAP_CLOSE(3PCAP)PCAP_CLOSE(3PCAP)pcap_close - close a capture device or savefile
#include <pcap/pcap.h>void pcap_close(pcap_t *p);
pcap_close() closes the files associated withp and deallocates resources. This means that, for example, ifp refers to a savefile that was opened withpcap_fopen_offline() orpcap_fopen_offline_with_tstamp_precision(), the stream provided to the routine will be closed unless it isstdin.
