)

[read]

wps_build_assoc_req_ie - Build WPS IE for (Re)Association Request : Value for Request Type attribute Returns: WPS IE or NULL on failure

The caller is responsible for freeing the buffer.

wps_build_probe_req_ie - Build WPS IE for Probe Request : Whether searching for PBC mode APs : Device attributes : Own UUID : Value for Request Type attribute Returns: WPS IE or NULL on failure

The caller is responsible for freeing the buffer.

struct wpabuf* wps_get_msg	(	struct wps_data *	wps,
		enum wsc_op_code *	op_code
	)			[read]

wps_get_msg - Build a WPS message : WPS Registration protocol data from wps_init() : Buffer for returning message OP Code Returns: The generated WPS message or NULL on failure

This function is used to build a response to a message processed by calling wps_process_msg(). The caller is responsible for freeing the buffer.

Definition at line 173 of file wps.c.

const u8* wps_get_uuid_e

(

const struct wpabuf *

msg

)

wps_get_uuid_e - Get UUID-E from WPS IE : WPS IE contents from Beacon or Probe Response frame Returns: Pointer to UUID-E or NULL if not included

The returned pointer is to the msg contents and it remains valid only as long as the msg buffer is valid.

struct wps_data* wps_init

(

const struct wps_config *

)

[read]

wps_init - Initialize WPS Registration protocol data : WPS configuration Returns: Pointer to allocated data or NULL on failure

This function is used to initialize WPS data for a registration protocol instance (i.e., each run of registration protocol as a Registrar of Enrollee. The caller is responsible for freeing this data after the registration run has been completed by calling wps_deinit().

enum wps_process_res wps_process_msg	(	struct wps_data *	wps,
		enum wsc_op_code	op_code,
		const struct wpabuf *	msg
	)

wps_process_msg - Process a WPS message : WPS Registration protocol data from wps_init() : Message OP Code : Message data Returns: Processing result

This function is used to process WPS messages with OP Codes WSC_ACK, WSC_NACK, WSC_MSG, and WSC_Done. The caller (e.g., EAP server/peer) is responsible for reassembling the messages before calling this function. Response to this message is built by calling wps_get_msg().
