Function Documentation

struct wpa_scan_results* wpa_driver_nl80211_get_scan_results

(

void *

priv

)

Fetch the latest scan results.

Parameters

priv	Pointer to private wext data from wpa_driver_nl80211_init()

Returns

Scan results on success, -1 on failure

int wpa_driver_nl80211_scan	(	struct i802_bss *	bss,
		struct wpa_driver_scan_params *	params
	)

Request the driver to initiate scan.

Parameters

bss	Pointer to private driver data from wpa_driver_nl80211_init()
params	Scan parameters

Returns

0 on success, -1 on failure

void wpa_driver_nl80211_scan_timeout	(	void *	eloop_ctx,
		void *	timeout_ctx
	)

Scan timeout to report scan completion.

Parameters

eloop_ctx	Driver private data
timeout_ctx	ctx argument given to wpa_driver_nl80211_init()

This function can be used as registered timeout when starting a scan to generate a scan completed event if the driver does not report this.

int wpa_driver_nl80211_sched_scan	(	void *	priv,
		struct wpa_driver_scan_params *	params,
		u32	interval
	)

Initiate a scheduled scan.

Parameters

priv	Pointer to private driver data from wpa_driver_nl80211_init()
params	Scan parameters
interval	Interval between scan cycles in milliseconds

Returns

0 on success, -1 on failure or if not supported

int wpa_driver_nl80211_stop_sched_scan

(

void *

priv

)

Stop a scheduled scan.

Parameters

priv	Pointer to private driver data from wpa_driver_nl80211_init()

Returns

0 on success, -1 on failure or if not supported
