xcb_xf86dri_query_direct_rendering_capable(3) XCB Requests xcb_xf86dri_query_direct_rendering_capable(3)

xcb_xf86dri_query_direct_rendering_capable -

#include <xcb/xf86dri.h>

xcb_xf86dri_query_direct_rendering_capable_cookie_t xcb_xf86dri_query_direct_rendering_capable(xcb_connection_t * conn, uint32_t screen);

typedef struct xcb_xf86dri_query_direct_rendering_capable_reply_t { uint8_t response_type; uint8_t pad0; uint16_t sequence; uint32_t length; uint8_t is_capable; } xcb_xf86dri_query_direct_rendering_capable_reply_t;

xcb_xf86dri_query_direct_rendering_capable_reply_t *xcb_xf86dri_query_direct_rendering_capable_reply(xcb_connection_t * conn, xcb_xf86dri_query_direct_rendering_capable_cookie_t cookie, xcb_generic_error_t ** e);
 

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

response_type
The type of this reply, in this case XCB_XF86DRI_QUERY_DIRECT_RENDERING_CAPABLE. 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).
is_capable
TODO: NOT YET DOCUMENTED.

Returns an xcb_xf86dri_query_direct_rendering_capable_cookie_t. Errors have to be handled when calling the reply function xcb_xf86dri_query_direct_rendering_capable_reply.
If you want to handle errors in the event loop instead, use xcb_xf86dri_query_direct_rendering_capable_unchecked. See xcb-requests(3) for details.

This request does never generate any errors.

Generated from xf86dri.xml. Contact xcb@lists.freedesktop.org for corrections and improvements.
