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.
