Enumeration Type Documentation

if_address_type

enum if_address_type

Enumeration of supported interface address types.

Used to indicate whether an address is IPv4 or IPv6.

Enumerator
IF_AT_IPv4	IPv4 address (4 bytes).
IF_AT_IPv6	IPv6 address (16 bytes).

Function Documentation

capture_get_if_capabilities()

if_capabilities_t * capture_get_if_capabilities ( const char *  app_name, const char *  devname, bool  monitor_mode, const char *  auth_string, char **  err_primary_msg, char **  err_secondary_msg, void(*)(void)  update_cb  )

extern

Fetch the linktype list for the specified interface from a child process.

capture_get_if_list_capabilities()

GHashTable * capture_get_if_list_capabilities ( const char *  app_name, GList *  if_cap_queries, char **  err_primary_msg, char **  err_secondary_msg, void(*)(void)  update_cb  )

extern

Fetch the linktype list for the specified interface from a child process.

capture_interface_list()

GList * capture_interface_list ( const char *  app_name, int *  err, char **  err_str, void(*)(void)  update_cb  )

extern

Return the list of interfaces.

Local interfaces are fetched by running dumpcap. The remote and extcap interfaces are appended to the list after that.

if_addr_copy()

if_addr_t * if_addr_copy

(

const if_addr_t *

if_addr

)

Deep copy an if_addr_t.

if_info_copy()

if_info_t * if_info_copy

(

const if_info_t *

if_info

)

Deep copy an if_info_t.

if_info_free()

void if_info_free

(

if_info_t *

if_info

)

Free an if_info_t.

if_info_get()

if_info_t * if_info_get ( const char *  name )

extern

Get an if_info_t for a particular interface. (May require privilege, so should only be used by dumpcap.)

interface_list_copy()

GList * interface_list_copy

(

GList *

if_list

)

Deep copy an interface list
