pcap_is_swapped - find out whether a savefile has the native byte order

  #include <pcap/pcap.h>
  int pcap_is_swapped(pcap_t *p);

pcap_is_swapped*() returns true (*1) if p refers to a ``savefile’’ that uses a different byte order than the current system. For a live capture, it always returns false (0).

It must not be called on a pcap descriptor created by *pcap_create*(3PCAP) that has not yet been activated by *pcap_activate*(3PCAP).

pcap_is_swapped*() returns true (*1) or false (0) on success and PCAP_ERROR_NOT_ACTIVATED if called on a capture handle that has been created but not activated.
