xcb_dbe_swap_buffers(3) XCB Requests xcb_dbe_swap_buffers(3) NAME xcb_dbe_swap_buffers - Swaps front and back buffers SYNOPSIS #include <xcb/dbe.h> Request function xcb_void_cookie_t xcb_dbe_swap_buffers(xcb_connection_t *conn, uint32_t n_actions, const xcb_dbe_swap_info_t *actions); REQUEST ARGUMENTS conn The XCB connection to X11. n_actions Number of swap actions in actions. actions List of windows on which to swap buffers. DESCRIPTION Swaps the front and back buffers on the specified windows. The front and back buffers retain their ids, so that the window id continues to refer to the front buffer, while the back buffer id created by this ex- tension continues to refer to the back buffer. Back buffer contents is moved to the front buffer. Back buffer contents after the operation de- pends on the given swap action. The optimal swap action depends on how each frame is rendered. For example, if the buffer is cleared and fully overwritten on every frame, the "untouched" action, which throws away the buffer contents, would provide the best performance. To eliminate visual artifacts, the swap will occure during the monitor VSync, if the X server supports detecting it. RETURN VALUE Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop. If you want to handle errors directly with xcb_request_check instead, use xcb_dbe_swap_buffers_checked. See xcb-requests(3) for details. ERRORS This request does never generate any errors. SEE ALSO xcb-requests(3) AUTHOR Generated from dbe.xml. Contact xcb@lists.freedesktop.org for correc- tions and improvements.
