Reply datastructure

typedef struct xcb_xv_query_best_size_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint16_t actual_width;
    uint16_t actual_height;
} xcb_xv_query_best_size_reply_t;

Reply function

xcb_xv_query_best_size_reply_t *xcb_xv_query_best_size_reply(xcb_connection_t *conn, xcb_xv_query_best_size_cookie_t cookie, xcb_generic_error_t **e);

REQUEST ARGUMENTS

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

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

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