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 de‐
       tecting 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.
