glGetPointerv — return the address of the specified pointer
void glGetPointerv( | GLenum pname, |
GLvoid ** params); |
pname Specifies the array or buffer pointer to be returned. Accepted symbolic names are GL_COLOR_ARRAY_POINTER, GL_NORMAL_ARRAY_POINTER, GL_POINT_SIZE_ARRAY_POINTER_OES, GL_TEXTURE_COORD_ARRAY_POINTER, and GL_VERTEX_ARRAY_POINTER.
params Returns the pointer value specified by pname.
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.
Querying the GL_TEXTURE_COORD_ARRAY_POINTER returns the value for the active client texture unit.
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.
glGetPointerv is only supported if the OpenGL ES version number is 1.1 or greater.
The pointers are all client-side state.
The initial value for each pointer is 0.
