Data Structures | |
| struct | singleton |
Functions | |
| int | pcap_dispatch (pcap_t *p, int cnt, pcap_handler callback, u_char *user) |
| Collects a group of packets. Returns when cnt packets have been received or when the timeout set with pcap_open_live() expires. More... | |
| int | pcap_loop (pcap_t *p, int cnt, pcap_handler callback, u_char *user) |
| Collects a group of packets. Returns when cnt packets have been received, but doesn't respect the timeout set with pcap_open_live(), therefore it can block forever. More... | |
| void | pcap_oneshot (u_char *userData, const struct pcap_pkthdr *h, const u_char *pkt) |
| const u_char * | pcap_next (pcap_t *p, struct pcap_pkthdr *h) |
| Discouraged, use pcap_read_ex() instead. Returns the next available packet. More... | |
| int | pcap_datalink (pcap_t *p) |
| Returns the link layer of an adapter. More... | |
| int | pcap_snapshot (pcap_t *p) |
| Returns the dimension of the packet portion (in bytes) that is delivered to the application. More... | |
| int | pcap_is_swapped (pcap_t *p) |
| returns true if the current savefile uses a different byte order than the current system. More... | |
| int | pcap_major_version (pcap_t *p) |
| returns the major version number of the pcap library used to write the savefile. More... | |
| int | pcap_minor_version (pcap_t *p) |
| returns the minor version number of the pcap library used to write the savefile. More... | |
| FILE * | pcap_file (pcap_t *p) |
| Discouraged, use pcap_dump() instead. Returns the stdio stream of an offile capture. More... | |
| int | pcap_fileno (pcap_t *p) |
| Deprecated, handling the device descriptor directly is useless under Win32. Returns the file descriptor of a capture device. More... | |
| void | pcap_perror (pcap_t *p, char *prefix) |
| prints the text of the last pcap library error on stderr, prefixed by prefix. More... | |
| char * | pcap_geterr (pcap_t *p) |
| returns the error text pertaining to the last pcap library error. More... | |
| int | pcap_getnonblock (pcap_t *p, char *errbuf) |
| Gets the "non-blocking" state of an interface. More... | |
| int | pcap_setnonblock (pcap_t *p, int nonblock, char *errbuf) |
| Switches between blocking and nonblocking mode. More... | |
| char * | pcap_win32strerror (void) |
| char * | pcap_strerror (int errnum) |
| pcap_strerror() is provided in case strerror() isn't available. More... | |
| pcap_t * | pcap_open_dead (int linktype, int snaplen) |
| Creates a pcap_t structure without starting a capture. More... | |
| void | pcap_close (pcap_t *p) |
| closes the files associated with p and deallocates resources. More... | |
