libwifi_create_timing_advert()

int libwifi_create_timing_advert	(	struct libwifi_timing_advert *	adv,
		const unsigned char	receiver[6],
		const unsigned char	transmitter[6],
		const unsigned char	address3[6],
		struct libwifi_timing_advert_fields *	adv_fields,
		const char	country[3],
		uint16_t	max_reg_power,
		uint8_t	max_tx_power,
		uint8_t	tx_power_used,
		uint8_t	noise_floor
	)

Create a populated libwifi_timing_advert struct.

A generated libwifi timing advert can be "dumped" into a buffer for packet injection via the libwifi_dump_timing_advert function.

Parameters

adv	A new libwifi_timing_advert struct
receiver	The receiver MAC address, aka address 1
transmitter	The source MAC address, aka address 2
address3	The address 3 frame field value, typically the BSSID
adv_fields	A libwifi_timing_advert_fields struct
country	The ISO 3166-1 country code field value
max_reg_power	Maximum Regulatory Power value
max_tx_power	Maximum Transmit Power value
tx_power_used	Transmit Power Used value
noise_floor	Noise Floor value

Returns

Zero on success, or negative errno

libwifi_dump_timing_advert()

size_t libwifi_dump_timing_advert	(	struct libwifi_timing_advert *	adv,
		unsigned char *	buf,
		size_t	buf_len
	)

Dump a libwifi_timing_advert into a raw format for packet injection.

Parameters

adv	A libwifi_timing_advert
buf	The output buffer for the frame data
buf_len	The length of the output buffer

Returns

The length of the dumped timing advert, or negative error

Definition at line 100 of file timing_ad.c.

libwifi_free_timing_advert()

void libwifi_free_timing_advert

(

struct libwifi_timing_advert *

adv

)

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

Parameters

adv	A libwifi_timing_advert struct

adv

)

Get the length of the specified libwifi_timing_advert struct.

Returns

Length of the specified timing advert, or negative error
