GLGETPOINTERV(3G)														 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_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 constant 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.
