GLGETPOINTERV(3G)		 OpenGL Manual		     GLGETPOINTERV(3G)

NAME
       glGetPointerv - return the address of the specified pointer

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

PARAMETERS
       pname
	   Specifies the array or buffer pointer to be returned. Symbolic
	   constants GL_COLOR_ARRAY_POINTER, GL_EDGE_FLAG_ARRAY_POINTER,
	   GL_FOG_COORD_ARRAY_POINTER, GL_FEEDBACK_BUFFER_POINTER,
	   GL_INDEX_ARRAY_POINTER, GL_NORMAL_ARRAY_POINTER,
	   GL_SECONDARY_COLOR_ARRAY_POINTER, GL_SELECTION_BUFFER_POINTER,
	   GL_TEXTURE_COORD_ARRAY_POINTER, or GL_VERTEX_ARRAY_POINTER are
	   accepted.

       params
	   Returns the pointer value specified by pname.

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

       For all pname arguments except GL_FEEDBACK_BUFFER_POINTER and
       GL_SELECTION_BUFFER_POINTER, if a non-zero named buffer object was
       bound to the GL_ARRAY_BUFFER target (see glBindBuffer()) when the
       desired pointer was previously specified, the pointer returned is a
       byte offset into the buffer object's data store. Buffer objects are
       only available in OpenGL versions 1.5 and greater.

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

       GL_FOG_COORD_ARRAY_POINTER and GL_SECONDARY_COLOR_ARRAY_POINTER are
       available only if the GL version is 1.4 or greater.

       The pointers are all client-side state.

       The initial value for each pointer is 0.

       For OpenGL versions 1.3 and greater, or when the 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.
