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
extension continues to refer to the back buffer. Back buffer contents
is moved to the front buffer. Back buffer contents after the operation
depends 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.
