XdbeAllocateBackBufferName(3)	  X Version 11	   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  XdbeSwapBuffers(3).   The
     actual  swap action used in calls to XdbeSwapBuffers(3) does not have to be
     the same as the swap_action passed to this function, though clients are en-
     couraged 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.

     BadValue
	    An invalid swap action was specified.

     BadWindow
	    An invalid window was specified.
