eap_tlv_build_nak - Build EAP-TLV NAK message : EAP identifier for the header : TLV type (EAP_TLV_*) Returns: Buffer to the allocated EAP-TLV NAK message or NULL on failure

This funtion builds an EAP-TLV NAK message. The caller is responsible for freeing the returned buffer.

eap_tlv_build_result - Build EAP-TLV Result message : EAP identifier for the header : Status (EAP_TLV_RESULT_SUCCESS or EAP_TLV_RESULT_FAILURE) Returns: Buffer to the allocated EAP-TLV Result message or NULL on failure

This funtion builds an EAP-TLV Result message. The caller is responsible for freeing the returned buffer.

	)			[static]

eap_tlv_process - Process a received EAP-TLV message and generate a response : Pointer to EAP state machine allocated with eap_peer_sm_init() : Return values from EAP request validation and processing : EAP-TLV request to be processed. The caller must have validated that the buffer is large enough to contain full request (hdr->length bytes) and that the EAP type is EAP_TYPE_TLV. : Buffer to return a pointer to the allocated response message. This field should be initialized to NULL before the call. The value will be updated if a response message is generated. The caller is responsible for freeing the allocated message. : Force negotiation to fail Returns: 0 on success, -1 on failure
