Retrieves information from the currently bound interface.

int Apple80211GetInfoCopy(struct Apple80211 *handle, CFDictionaryRef *info);

Parameters

• handle An open handle from an Apple80211Open call, that has also been bound to an interface using Apple80211BindToInterface
• info A (returned) pointer to a CFDictionary containing the information

Returns

• 0 if successful, who knows what else otherwise (seems to be -1 if it doesn't crash)
• info a CFDictionaryRef containing key/value pairs of information about the interface (see below)

Known CFDictionary keys for info

All keys are CFStrings

• STATE - An integer CFNumber indicating the state of the device. Its value is 4 if the interface is associated
• SSID_STR - A CFString containing the network name the interface is currently associated with (may be absent if the interface is not associated)
• POWER - A CFArray that appears to contain one CFNumber (not sure what it means)
• BSSID - A CFString containing a colon-separated BSSID (MAC address) of the currently associated network (may be absent if the interface is not associated)
• TXPOWER - An integer CFNumber containing the current transmit power?
• POWERSAVE - An integer CFNumber indicating whether the device is currently in power saving mode?
• RSSI - A CFDictionary of information on the signal strength
• AUTH_TYPE - A CFDictionary of information on the authentication type?
• SSID - A CFData containing the currently associated SSID in an unknown format
• CHANNEL - A CFDictionary containing the channel and channel flags (the flags are currently unknown)
• RATE - An integer CFNumber containing the current rate of the connection (seems to be in megabits per second)

Sample Output

The following is the output of a CFShow on the returned CFDictionaryRef:
