pcap_freecode - free a BPF program

  #include <pcap/pcap.h>
  void pcap_freecode(struct bpf_program *);

*pcap_freecode*() is used to free up allocated memory pointed to by a bpf_program struct generated by *pcap_compile*(3PCAP) when that BPF program is no longer needed, for example after it has been made the filter program for a pcap structure by a call to *pcap_setfilter*(3PCAP).
