XdbeAllocateBackBufferName(3)	  X FUNCTIONS	 XdbeAllocateBackBufferName(3)

NAME
       XdbeAllocateBackBufferName - allocates a	DBE buffer.

SYNOPSIS
       #include	<X11/extensions/Xdbe.h>

       XdbeBackBuffer XdbeAllocateBackBufferName(
	   Display	  *dpy,
	   Window	  window,
	   XdbeSwapAction swap_action)

DESCRIPTION
       This function returns a drawable	ID used	to refer to the	back buffer of
       the specified window.  The swap_action is a hint	to indicate  the  swap
       action  that  will  likely  be  used  in	 subsequent calls to XdbeSwap-
       Buffers().  The actual swap action used in calls	 to  XdbeSwapBuffers()
       does  not  have	to be the same as the swap_action passed to this func-
       tion, though clients are	encouraged  to	provide	 accurate  information
       whenever	possible.

ERRORS

       BadMatch
	      The  specified window is not an InputOutput window or its	visual
	      does not support DBE.

	      An invalid swap action was specified.

       BadWindow
