glGetPointerv 3G
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. Accepted symbolic names are `GL_COLOR_ARRAY_POINTER`, `GL_MATRIX_INDEX_ARRAY_POINTER_OES`, `GL_NORMAL_ARRAY_POINTER`, `GL_POINT_SIZE_ARRAY_POINTER_OES`, `GL_TEXTURE_COORD_ARRAY_POINTER`, and `GL_VERTEX_ARRAY_POINTER`., and `GL_WEIGHT_ARRAY_POINTER_OES`.

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.

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.

## Notes

`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.

## Errors

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