NAME
       glGetPointerv - return the address of the specified pointer

SYNOPSIS
       void glGetPointerv(
	       GLenum pname,
	       GLvoid* *params );

PARAMETERS
       Specifies  the  array  or  buffer pointer to be returned. Symbolic con‐
       stants  GL_COLOR_ARRAY_POINTER,	GL_EDGE_FLAG_ARRAY_POINTER,   GL_FEED‐
       BACK_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.  Returns the pointer value speci‐
       fied 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.
