NAME
	  glXGetClientString - return a	string describing the client


     C SPECIFICATION
	  const	char * glXGetClientString( Display *dpy,
					   int name )


     PARAMETERS
	  dpy	Specifies the connection to the	X server.

	  name	Specifies which	string is returned.  One of
		GLX_VENDOR, GLX_VERSION, or GLX_EXTENSIONS.

     DESCRIPTION
	  glXGetClientString returns a string describing some aspect
	  of the client	library. The possible values for name are
	  GLX_VENDOR, GLX_VERSION, and GLX_EXTENSIONS. If name is not
	  set to one of	these values, glXGetClientString returns NULL.
	  The format and contents of the vendor	string is
	  implementation dependent.

	  The extensions string	is null-terminated and contains	a
	  space-separated list of  extension names. (The extension
	  names	never contain spaces.) If there	are no extensions to
	  GLX, then the	empty string is	returned.

	  The version string is	laid out as follows:

	  <major_version.minor_version><space><vendor-specific info>

	  Both the major and minor portions of the version number are
	  of arbitrary length.	The vendor-specific information	is
	  optional.  However, if it is present,	the format and
	  contents are implementation specific.

     NOTES
	  glXGetClientString is	available only if the GLX version is
	  1.1 or greater.

	  If the GLX version is	1.1 or 1.0, the	GL version must	be
	  1.0.	If the GLX version is 1.2, then	the GL version must be
	  1.1.

	  glXGetClientString only returns information about GLX
	  extensions supported by the client. Call glGetString to get
	  a list of GL extensions supported by the server.
