GLXCREATEGLXPIXMAP()			 GLXCREATEGLXPIXMAP()

NAME
       glXCreateGLXPixmap  -  create  an off-screen GLX rendering
       area

C SPECIFICATION
       GLXPixmap glXCreateGLXPixmap( Display *dpy,
				     XVisualInfo *vis,
				     Pixmap pixmap )

PARAMETERS
       dpy     Specifies the connection to the X server.

       vis     Specifies the visual that defines the structure of
	       the  rendering area.  It is a pointer to an XVisu-
	       alInfo structure, not a visual ID or a pointer  to
	       a Visual.

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

DESCRIPTION
       glXCreateGLXPixmap  creates  an	off-screen rendering area
       and returns its XID.  Any GLX rendering context	that  was
       created	with  respect  to  vis can be used to render into
       this off-screen area.  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  vis, including  color
       buffers other than the  front  left  buffer,  are  created
       without	externally  visible names.  GLX pixmaps with dou-
       ble-buffering are supported.  However,  glXSwapBuffers  is
       ignored by these pixmaps.

       Some  implementations  may  not	support GLX pixmaps with
       direct rendering contexts.

NOTES
       XVisualInfo is defined in Xutil.h.  It is a structure that
       includes visual, visualID, screen, and depth elements.

ERRORS
       BadMatch is  generated	if  the depth of pixmap does not
       match the depth value reported by core X11 for vis, or  if
       pixmap  was not created with respect to the same screen as
       vis.

       BadValue is generated if vis is not  a  valid  XVisualInfo
       pointer	(for  example, if a particular GLX implementation
       does not support this visual).

       BadPixmap is generated if pixmap is not a valid pixmap.

       BadAlloc is generated if the server  cannot  allocate  the
       GLX pixmap.
