NAME
       glGetPointerv - return the address of the specified pointer


C SPECIFICATION
       void glGetPointerv( GLenum pname,
			   void **params )


PARAMETERS
       pname   Specifies  the  array  or buffer pointer to be returned.	 Sym-
	       bolic		constants	      GL_COLOR_ARRAY_POINTER,
	       GL_EDGE_FLAG_ARRAY_POINTER,	  GL_FEEDBACK_BUFFER_POINTER,
	       GL_INDEX_ARRAY_POINTER,		     GL_NORMAL_ARRAY_POINTER,
	       GL_TEXTURE_COORD_ARRAY_POINTER,	 GL_SELECTION_BUFFER_POINTER,
	       and GL_VERTEX_ARRAY_POINTER are accepted.

       params  Returns the pointer value specified by pname.

DESCRIPTION
       glGetPointerv returns pointer information. pname is  a  symbolic	 con-
       stant  indicating  the pointer to be returned, and params is a pointer
       to a location in which to place the returned data.

NOTES
       glGetPointerv is available only if the GL version is 1.1 or greater.

       The pointers are all client-side state.

       The initial value for each pointer is 0.

       When the GL_ARB_multitexture  extension	is  supported,	querying  the
       GL_TEXTURE_COORD_ARRAY_POINTER returns the value for the active client
       texture unit.

ERRORS
       GL_INVALID_ENUM is generated if pname is not an accepted value.
