glGetPointervEXT(3G)

NAME
     glGetPointervEXT - return the address of a buffer or vertex array


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


PARAMETERS
     pname   Specifies the 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, and
             GL_INSTRUMENT_BUFFER_POINTER_SGIX are accepted.

     params  returns the pointer value specified by pname.


DESCRIPTION
     glGetPointervEXT 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
     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.

     Similarly, GL_INSTRUMENT_BUFFER_POINTER_SGIX is part of the
     SGIX_ir_instrument1 extension.

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