glXBindChannelToWindowSGIX(3G)				OpenGL Reference - GLX

NAME    [Toc]    [Back]

     glXBindChannelToWindowSGIX	- bind or unbind a window and a	channel

C SPECIFICATION    [Toc]    [Back]

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

PARAMETERS    [Toc]    [Back]

     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    [Toc]    [Back]

     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    [Toc]    [Back]

     glXBindChannelToWindowSGIX	is part	of the SGIX_video_resize extension.



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