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().   The  actual  swap  action  used  in  calls  to
       XdbeSwapBuffers() does not have to be the same as the swap_action passed to this function,
       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

       BadValue
              An invalid swap action was specified.
