NAME
	  glXImportContextEXT -	import another process's indirect
	  rendering context.


     C SPECIFICATION
	  GLXContext glXImportContextEXT( Display *dpy,
					  GLXContextID contextID )


     PARAMETERS
	  dpy	     Specifies the connection to the X server.


	  contextID  Specifies a GLX rendering context.


     DESCRIPTION
	  glXImportContextEXT creates a	GLXContext given the XID of an
	  existing GLXContext.	It may be used in place	of
	  glXCreateContext, to share another process's indirect
	  rendering context.

	  Only the server-side context information can be shared
	  between X clients; client-side state,	such as	pixel storage
	  modes, cannot	be shared. Thus, glXImportContextEXT must
	  allocate memory to store client-side information. This
	  memory is freed by calling glXFreeContextEXT.

	  This call does not create a new XID.	It merely makes	an
	  existing object available to the importing client (Display
	  *).  Like any	XID, it	goes away when the creating client
	  drops	its connection or the ID is explicitly deleted.	Note
	  that this is when the	XID goes away. The object goes away
	  when the XID goes away AND the context is not	current	to any
	  thread.

	  If contextID refers to a direct rendering context then no
	  error	is generated but glXImportContextEXT returns NULL.

	  glXImportContextEXT is part of the EXT_import_context
	  extension, not part of the core GLX command set. If
	  GLX_EXT_import_context is included in	the string returned by
	  glXQueryExtensionsString, when called	with argument
	  GLX_EXTENSIONS, extension EXT_import_context is supported.


     ERRORS
	  GLXBadContext	is generated if	contextID does not refer to a
	  valid	context.
