glXBindChannelToWindowSGIX(3G)

NAME
     glXBindChannelToWindowSGIX - bind or unbind a window and a channel


C SPECIFICATION
     int glXBindChannelToWindowSGIX( Display *dpy,
                                     int screen,
                                     int channel,
                                     Window window )


PARAMETERS
     dpy      Specifies the connection to the X server.

     screen   Specifies the screen of the X server.

     channel  Specifies the video channel number.

     window   Specifies the window that is to be bound to channel


DESCRIPTION
     If window is not NULL, glXBindChannelToWindowSGIX binds window to
     channel. Once channel is bound to a window, glXChannelRectSGIX can be
     called to set the rectangular area of the frame buffer that will be
     mapped to the resolution of the video when glXSwapBuffers is called for
     that window.

     If window is destroyed while bound to channel, then there is an implicit
     unbind, and any area set by glXChannelRectSGIX is reset to the default
     area specified by the video combination currently loaded.

     To unbind a channel and a window, call glXBindChannelToWindowSGIX with
     window set to NULL.


NOTES
     glXBindChannelToWindowSGIX is part of the SGIX_video_resize extension.



MACHINE DEPENDENCIES
     The SGIX_video_resize extension is supported only on InfiniteReality
     systems.
