xcb_input_query_device_state(3) XCB Requests xcb_input_query_device_state(3)

xcb_input_query_device_state -

#include <xcb/xinput.h>

xcb_input_query_device_state_cookie_t xcb_input_query_device_state(xcb_connection_t *conn, uint8_t device_id);


typedef struct xcb_input_query_device_state_reply_t {
    uint8_t  response_type;
    uint8_t  xi_reply_type;
    uint16_t sequence;
    uint32_t length;
    uint8_t  num_classes;
    uint8_t  pad0[23];
} xcb_input_query_device_state_reply_t;

xcb_input_query_device_state_reply_t *xcb_input_query_device_state_reply(xcb_connection_t *conn, xcb_input_query_device_state_cookie_t cookie, xcb_generic_error_t **e);

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);

conn
The XCB connection to X11.
device_id
TODO: NOT YET DOCUMENTED.

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.
length
The length of the reply, in words (a word is 4 bytes).
xi_reply_type
TODO: NOT YET DOCUMENTED.
num_classes
TODO: NOT YET DOCUMENTED.

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.

Generated from xinput.xml. Contact xcb@lists.freedesktop.org for corrections and improvements.
