glXCreateGLXPixmapWithConfigSGIX(3G)

NAME
     glXCreateGLXPixmapWithConfigSGIX - create an off-screen GLX rendering
     area with specified frame buffer configuration


C SPECIFICATION
     GLXPixmap glXCreateGLXPixmapWithConfigSGIX( Display *dpy,
                                                 GLXFBConfigSGIX config,
                                                 Pixmap pixmap )


PARAMETERS
     dpy     Specifies the connection to the X server.


     config  Specifies the GLX frame buffer configuration that defines the
             structure of the rendering area.


     pixmap  Specifies the X pixmap that will be used as the front left color
             buffer of the off-screen rendering area.


DESCRIPTION
     glXCreateGLXPixmapWithConfigSGIX creates an off-screen rendering area and
     returns its XID.  Use glXMakeCurrent to associate the rendering area with
     a GLX rendering context.

     The X pixmap identified by pixmap is used as the front left buffer of the
     resulting off-screen rendering area.  All other buffers specified by
     config, including color buffers other than the front left buffer, are
     created without externally visible names.  GLX pixmaps with double-
     buffering are supported.  However, glXSwapBuffers is ignored by these
     pixmaps.

     GLX pixmaps are not supported with direct rendering contexts.


NOTES
     glXCreateGLXPixmapWithConfigSGIX is part of the GLX_SGIX_fbconfig
     extension.


ERRORS
     BadMatch is generated if pixmap was not created with respect to the same
     screen as config.

     GLXBadFBConfigSGIX is generated if config is not a valid GLXFBConfig.

     BadPixmap is generated if pixmap is not a valid pixmap.
     BadAlloc is generated if the server cannot allocate the GLX pixmap.
