NAME
     glGetPointervEXT -	return the address of a	vertex data array


C SPECIFICATION
     void glGetPointervEXT( GLenum pname,
			    GLvoid* *params )


PARAMETERS
     pname   Specifies the array pointer to be returned.  Symbolic constants
	     GL_VERTEX_ARRAY_POINTER_EXT, GL_NORMAL_ARRAY_POINTER_EXT,
	     GL_COLOR_ARRAY_POINTER_EXT, GL_INDEX_ARRAY_POINTER_EXT,
	     GL_TEXTURE_COORD_ARRAY_POINTER_EXT,
	     GL_EDGE_FLAG_ARRAY_POINTER_EXT, are accepted.

     params  returns the array pointer value specified by pname.


DESCRIPTION
     glGetPointervEXT returns array pointer information. pname is a symbolic
     constant indicating the array pointer to be returned, and params is a
     pointer to	a location in which to place the returned data.

NOTES
     The array pointers	are client side	state.

     glGetPointervEXT is part of the EXT_vertex_array extension, not part of
     the core GL command set. If GL_EXT_vertex_array is	included in the	string
     returned by glGetString, when called with argument	GL_EXTENSIONS,
     extension EXT_vertex_array	is supported.

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