glXBindSwapBarrierSGIX(3G)

NAME
     glXBindSwapBarrierSGIX - synchronize buffer swaps with other screens


C SPECIFICATION
     void glXBindSwapBarrierSGIX( Display *dpy,
                                  GLXDrawable drawable,
                                  int barrier )


PARAMETERS
     dpy       Specifies the connection to the X server.


     drawable  Specifies any GLX drawable in the swap group.


     barrier   Specifies the barrier.


DESCRIPTION
     glXBindSwapBarrierSGIX is part of the SGIX_swap_barrier extension.

     glXBindSwapBarrierSGIX binds the swap group containing drawable to
     barrier.  Buffer swaps to all members of all groups bound to barrier will
     then take place concurrently, after all of their swap intervals have
     elapsed.  Typically, the other swap groups bound to a barrier will reside
     on other screens or hosts.  The parameter barrier must be greater than or
     equal to zero and less than or equal to the number of supported barriers
     returned by glXQueryMaxSwapBarriersSGIX.

     If barrier is zero, the swap group is bound to no barrier.

     glXBindSwapBarrierSGIX is part of the stream of X calls; to synchronize
     with OpenGL calls, use glXWaitX or glXWaitGL.


ERRORS
     GLXBadDrawable is generated if drawable is not a valid GLX drawable.

     BadValue is generated if barrier is already bound to another swap group,
     or if barrier is invalid.
