			<tt>gluGetString</tt> returns a pointer to a static string describing the GLU version or the GLU extensions
			that are supported.
		</p><p>
			The version number is one of the following forms:
		</p><p>
			<i><tt>major_number.minor_number</tt></i>
		</p><p>
			<i><tt>major_number.minor_number.release_number</tt></i>.
		</p><p>
			The version string is of the following form:
		</p><p>
			<i><tt>version number&lt;space&gt;vendor-specific information</tt></i>
		</p><p>
			Vendor-specific information is optional. Its format and contents depend on the implementation.
		</p><p>
			The standard GLU contains a basic set of features and capabilities. If a company or group of companies wish to support
			other features, these may be included as extensions to the GLU. If <i><tt>name</tt></i> is
			<tt>GLU_EXTENSIONS</tt>, then <tt>gluGetString</tt> returns a space-separated list of names of
			supported GLU extensions. (Extension names never contain spaces.)
		</p><p>
			All strings are <tt>NULL</tt>-terminated.
		</p></div><div class="refsect1" lang="en"><a name="gluGetString.3G-notes"/><h2>Notes</h2><p>
			<tt>gluGetString</tt> only returns information about GLU extensions. Call <a href="glGetString.3G.xml"><tt>glGetString</tt></a> to get a list of GL extensions.
		</p><p>
			<tt>gluGetString</tt> is an initialization routine. Calling it after a <a href="glNewList.3G.xml"><tt>glNewList</tt></a> results in undefined behavior.
		</p></div><div class="refsect1" lang="en"><a name="gluGetString.3G-errors"/><h2>Errors</h2><p>
			<tt>NULL</tt> is returned if <i><tt>name</tt></i> is not <tt>GLU_VERSION</tt> or
