bionic (3) XdbeAllocateBackBufferName.3.gz

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 DBE.

       BadValue
              An invalid swap action was specified.

       BadWindow
