xcb_dri2_copy_region(3) XCB Requests xcb_dri2_copy_region(3)

xcb_dri2_copy_region -

#include <xcb/dri2.h>

xcb_dri2_copy_region_cookie_t xcb_dri2_copy_region(xcb_connection_t * conn, xcb_drawable_t  drawable, uint32_t region, uint32_t  dest, uint32_t src);

typedef struct xcb_dri2_copy_region_reply_t { uint8_t response_type; uint8_t pad0; uint16_t sequence; uint32_t length; } xcb_dri2_copy_region_reply_t;

xcb_dri2_copy_region_reply_t *xcb_dri2_copy_region_reply(xcb_connection_t * conn, xcb_dri2_copy_region_cookie_t  cookie, xcb_generic_error_t ** e);
 

conn
The XCB connection to X11.
drawable
TODO: NOT YET DOCUMENTED.
region
TODO: NOT YET DOCUMENTED.
dest
TODO: NOT YET DOCUMENTED.
src
TODO: NOT YET DOCUMENTED.

response_type
The type of this reply, in this case XCB_DRI2_COPY_REGION. 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).

Returns an xcb_dri2_copy_region_cookie_t. Errors have to be handled when calling the reply function xcb_dri2_copy_region_reply.
If you want to handle errors in the event loop instead, use xcb_dri2_copy_region_unchecked. See xcb-requests(3) for details.

This request does never generate any errors.

Generated from dri2.xml. Contact xcb@lists.freedesktop.org for corrections and improvements.
