u8* gas_anqp_add_element	(	struct wpabuf *	buf,
		u16	info_id
	)

Add ANQP element header.

Parameters

buf	GAS message
info_id	ANQP Info ID

Returns

Pointer to the Length field for gas_anqp_set_element_len()

void gas_anqp_set_element_len	(	struct wpabuf *	buf,
		u8 *	len_pos
	)

Update ANQP element Length field.

Parameters

buf	GAS message
len_pos	Length field position from gas_anqp_add_element()

This function is called after the ANQP element payload has been added to the buffer.

void gas_anqp_set_len

(

struct wpabuf *

buf

)

Set Query Request/Response Length.

Parameters

buf	GAS message

This function is used to update the Query Request/Response Length field once the payload has been filled.
