glxswapbuffers (3)

    NAME
         glXSwapBuffers - make back buffer visible
    
    
    C SPECIFICATION
         void glXSwapBuffers( Display *dpy,
                              GLXDrawable drawable )
    
    
    PARAMETERS
         dpy       Specifies the connection to the X server.
    
         drawable  Specifies the drawable whose  buffers  are  to  be
                   swapped.
    
    DESCRIPTION
         glXSwapBuffers promotes the contents of the back  buffer  of
         drawable to become the contents of the front buffer of draw-
         able.  The contents of the back  buffer  then  become  unde-
         fined.  The update typically takes place during the vertical
         retrace  of  the  monitor,  rather  than  immediately  after
         glXSwapBuffers  is called.  All GLX rendering contexts share
         the same notion of which are front  buffers  and  which  are
         back buffers.
    
         glXSwapBuffers  performs  an  implicit  glFlush  before   it
         returns.   Subsequent  GL commands can be issued immediately
         after calling glXSwapBuffers, but are not executed until the
         buffer exchange is completed.
    
         If drawable was  not  created  with  respect  to  a  double-
         buffered  visual, glXSwapBuffers has no effect, and no error
         is generated.
    
    NOTES
         Synchronization of multiple GLX contexts  rendering  to  the
         same  double-buffered  window  is  the responsibility of the
         clients.  Use the X Synchronization Extension to  facilitate
         such cooperation.
    
         The X double buffer extension (DBE) has information on which
         buffer  is  the currently displayed buffer. This information
         is shared with GLX.
    
    ERRORS
         GLXBadDrawable is generated if drawable is not a  valid  GLX
         drawable.
    
         GLXBadCurrentWindow is generated if  dpy  and  drawable  are
         respectively  the  display  and drawable associated with the
         current context of the calling thread, and drawable  identi-
         fies a window that is no longer valid.
