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
       BadAlloc

       BadIDChoice

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

	      An invalid swap action was specified.

       BadWindow
