XdbeAllocateBackBufferName(3X11)

     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.
