glGetPointerv - OpenGL 4 Reference Pages

## Name

glGetPointerv — return the address of the specified pointer

## C Specification

`void glGetPointerv(` | GLenum pname,
| GLvoid ** params`)`;

## Parameters

`pname`

  Specifies the pointer to be returned. Must be one of `GL_DEBUG_CALLBACK_FUNCTION` or `GL_DEBUG_CALLBACK_USER_PARAM`.

`params`

  Returns the pointer value specified by `pname`.

## Description

`glGetPointerv` returns pointer information. `pname` indicates the pointer to be returned, and `params` is a pointer to a location in which to place the returned data. The parameters that may be queried include:

`GL_DEBUG_CALLBACK_FUNCTION`

  Returns the current callback function set with the `callback` argument of glDebugMessageCallback.

`GL_DEBUG_CALLBACK_USER_PARAM`

  Returns the user parameter to the current callback function set with the `userParam` argument of glDebugMessageCallback.

## Notes

`glGetPointerv` is available in the OpenGL core profile only if the GL version is 4.3 or later. It is available in the compatibility profile for all GL versions, and accepts additional queries. However, these reference pages document only the core profile.

## Errors

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