wps_registrar_init - Initialize WPS Registrar data : Pointer to longterm WPS context : Registrar configuration Returns: Pointer to allocated Registrar data or NULL on failure

This function is used to initialize WPS Registrar functionality. It can be used for a single Registrar run (e.g., when run in a supplicant) or multiple runs (e.g., when run as an internal Registrar in an AP). Caller is responsible for freeing the returned data with wps_registrar_deinit() when Registrar functionality is not needed anymore.

wps_registrar_probe_req_rx - Notify Registrar of Probe Request : Registrar data from wps_registrar_init() : MAC address of the Probe Request sender : WPS IE contents

This function is called on an AP when a Probe Request with WPS IE is received. This is used to track PBC mode use and to detect possible overlap situation with other WPS APs.

)

wps_registrar_unlock_pin - Unlock a PIN for a specific UUID-E : Registrar data from wps_registrar_init() : UUID-E Returns: 0 on success, -1 on failure

PINs are locked to enforce only one concurrent use. This function unlocks a PIN to allow it to be used again. If the specified PIN was configured using a wildcard UUID, it will be removed instead of allowing multiple uses.
