Function Documentation

libwifi_create_probe_req()

int libwifi_create_probe_req	(	struct libwifi_probe_req *	probe_req,
		const unsigned char	receiver[6],
		const unsigned char	transmitter[6],
		const unsigned char	address3[6],
		const char *	ssid,
		uint8_t	channel
	)

The generated probe request frame is made with sane defaults defined in common.h.

Generate a populated libwifi probe_req.

Two tagged parameters are also added to the beacon: SSID and Channel.

libwifi_dump_probe_req()

size_t libwifi_dump_probe_req	(	struct libwifi_probe_req *	probe_req,
		unsigned char *	buf,
		size_t	buf_len
	)

Copy a libwifi_probe_req into a regular unsigned char buffer.

Dump a libwifi_probe_req into a raw format for packet injection.

This is useful when injecting generated libwifi frames.

libwifi_free_probe_req()

void libwifi_free_probe_req

(

struct libwifi_probe_req *

probe_req

)

Because the tagged parameters memory is managed inside of the library, the library must be the one to free it, too.

Free any memory claimed by a libwifi_probe_req back to the system.

libwifi_get_probe_req_length()

size_t libwifi_get_probe_req_length

(

struct libwifi_probe_req *

probe_req

)

The length of a probe request frame is the sum of the header length plus the tagged parameters length.

Calculate the length of a given libwifi_probe_req.
