Detailed Description

Sync mode capture (internal interface).

Will start a new Wireshark child instance which will do the actual capture work.

Function Documentation

◆ sync_if_capabilities_open()

int sync_if_capabilities_open	(	const char *	ifname,
		bool	monitor_mode,
		const char *	auth,
		char **	data,
		char **	primary_msg,
		char **	secondary_msg,
		void(*)(void)	update_cb
	)

Get interface capabilities using dumpcap

◆ sync_interface_list_open()

int sync_interface_list_open	(	char **	data,
		char **	primary_msg,
		char **	secondary_msg,
		void(*)(void)	update_cb
	)

Get an interface list using dumpcap

◆ sync_interface_set_80211_chan()

int sync_interface_set_80211_chan	(	const char *	iface,
		const char *	freq,
		const char *	type,
		const char *	center_freq1,
		const char *	center_freq2,
		char **	data,
		char **	primary_msg,
		char **	secondary_msg,
		void(*)(void)	update_cb
	)

Set wireless channel using dumpcap On success, *data points to a buffer containing the dumpcap output, *primary_msg and *secondary_msg are NULL, and 0 is returned. *data must be freed with g_free().

On failure, *data is NULL, *primary_msg points to an error message, *secondary_msg either points to an additional error message or is NULL, and -1 or errno value is returned; *primary_msg, and *secondary_msg if not NULL must be freed with g_free().

Parameters

iface	(monitor) network interface name
freq	channel control frequency string (in MHz)
type	channel type string (or NULL if not used)
center_freq1	VHT channel center frequency (or NULL if not used)
center_freq2	VHT channel center frequency 2 (or NULL if not used)
data	On success, data points to a buffer containing the dumpcap output, On failure data is NULL
primary_msg	On success NULL, On failure points to an error message
secondary_msg	On success NULL, On failure either points to an additional error message or is NULL
update_cb	update callback

Returns: 0 on success

◆ sync_interface_stats_close()

int sync_interface_stats_close	(	int *	read_fd,
		ws_process_id *	fork_child,
		char **	msg
	)

Stop gathering statistics.

◆ sync_interface_stats_open()

int sync_interface_stats_open	(	int *	read_fd,
		ws_process_id *	fork_child,
		char **	data,
		char **	msg,
		void(*)(void)	update_cb
	)

Start getting interface statistics using dumpcap.

◆ sync_pipe_gets_nonblock()

int sync_pipe_gets_nonblock	(	int	pipe_fd,
		char *	bytes,
		int	max
	)

Read a line from a pipe, similar to fgets. Non-blocking.

◆ sync_pipe_kill()

void sync_pipe_kill ( ws_process_id fork_child )

User wants to stop the program, just kill the child as soon as possible

◆ sync_pipe_start()

bool sync_pipe_start	(	capture_options *	capture_opts,
		GPtrArray *	capture_comments,
		capture_session *	cap_session,
		struct _info_data *	cap_data,
		void(*)(void)	update_cb
	)

Start a new capture session. Create a capture child which is doing the real capture work. The various capture_input_... functions will be called, if something had happened.

Most of the parameters are passed through the global capture_opts.
