PyOpenGL does not export a binding for <tt>glGetPointerv</tt> since all memory management for array
functions and buffer functions and handled automatically. For more information see
??? and ???.

<tt>glGetPointerv</tt> returns pointer information. <i><tt>pname</tt></i> is a symbolic constant
indicating the pointer to be returned, and <i><tt>params</tt></i> is a pointer to a location in which to place
the returned data.
</p></div><div class="refsect1" lang="en"><a name="glGetPointerv.3G-notes"/><h2>Notes</h2><p>
<tt>glGetPointerv</tt> is available only if the GL version is 1.1 or greater.
</p><p>
The pointers are all client-side state.
</p><p>
The initial value for each pointer is 0.
</p><p>
When the <tt>GL_ARB_multitexture</tt> extension is supported, querying the
<tt>GL_TEXTURE_COORD_ARRAY_POINTER</tt> returns the value for the active client texture unit.
</p></div><div class="refsect1" lang="en"><a name="glGetPointerv.3G-errors"/><h2>Errors</h2><p>
<tt>GL_INVALID_ENUM</tt> is generated if <i><tt>pname</tt></i> is not an accepted value.
