Macro Definition Documentation

WS80211_INIT_OK

#define WS80211_INIT_OK   0

Initialize the 802.11 environment. On Linux this initializes an nl80211_state struct.

Returns

WS80211_INIT_OK on success, WS80211_INIT_NOT_SUPPORTED if the 802.11 environment isn't supported, or the negative of an errno value on failure.

Function Documentation

ws80211_find_interfaces()

GArray * ws80211_find_interfaces

(

void

)

Build a list of 802.11 interfaces.

Returns

A GArray of pointers to struct ws80211_interface on success, NULL on failure.

ws80211_free_interfaces()

void ws80211_free_interfaces

(

GArray *

interfaces

)

Free an interface list.

Parameters

interfaces

A list of interfaces created with ws80211_find_interfaces().

ws80211_get_helper_path()

const char * ws80211_get_helper_path

(

void

)

Get the path to a helper application. Return the path to a separate 802.11 helper application, e.g. the GNOME Network Manager.

Returns

The path to the helper on success, NULL on failure.

ws80211_has_fcs_filter()

bool ws80211_has_fcs_filter

(

void

)

Check to see if we have FCS filtering.

Returns

true if FCS filtering is supported on this platform.

ws80211_set_fcs_validation()

int ws80211_set_fcs_validation	(	const char *	name,
		enum ws80211_fcs_validation	fcs_validation
	)

Set the FCS validation behavior for an interface.

Parameters

name	The interface name.
fcs_validation	The desired validation behavior.

Returns

Zero on success, nonzero on failure.

ws80211_set_freq()

int ws80211_set_freq	(	const char *	name,
		uint32_t	freq,
		int	chan_type,
		uint32_t _U_	center_freq,
		uint32_t _U_	center_freq2
	)

Set the frequency and channel width for an interface.

Parameters

name	The interface name.
freq	The frequency in MHz.
chan_type	The HT channel type (no, 20Mhz, 40Mhz...).
center_freq	The center frequency in MHz (if 80MHz, 80+80MHz or 160MHz).
center_freq2	The 2nd center frequency in MHz (if 80+80MHz).

Returns

Zero on success, nonzero on failure.
