xcb_input_query_device_state_unchecked(3)

Usage

xcb_input_query_device_state_cookie_t xcb_input_query_device_state(xcb_connection_t *conn, uint8_t device_id);

uint8_t response_type;

uint8_t xi_reply_type;

uint16_t sequence;

uint32_t length;

uint8_t num_classes;

uint8_t pad0 [23] ;

int xcb_input_query_device_state_classes_length(const xcb_input_query_device_state_reply_t *reply);

xcb_input_input_state_iterator_t xcb_input_query_device_state_classes_iterator(const xcb_input_query_device_state_reply_t *reply);

response_type: The type of this reply, in this case XCB_INPUT_QUERY_DEVICE_STATE. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other.

sequence: The sequence number of the last request processed by the X11 server.

Returns an xcb_input_query_device_state_cookie_t. Errors have to be handled when calling the reply function xcb_input_query_device_state_reply.

If you want to handle errors in the event loop instead, use xcb_input_query_device_state_unchecked. See xcb-requests(3) for details.

This request does never generate any errors.
