glXBindChannelToWindowSGIX(3G) OpenGL Reference - GLX
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.
