7 <code class=
"function">gluGetString
</code> returns a pointer to a static string describing the
8 GLU version or the GLU extensions that are supported.
10 The version number is one of the following
13 <span class=
"emphasis"><em>major_number.minor_number
</em></span>
14 <span class=
"emphasis"><em>major_number.minor_number.release_number
</em></span>.
16 The version string is of the following form:
18 <span class=
"emphasis"><em>version number
<space
>vendor-specific information
</em></span>
20 Vendor-specific information is optional.
21 Its format and contents depend on the implementation.
23 The standard GLU contains a basic set of features and capabilities.
24 If a company or group of companies wish to support other features,
25 these may be included as extensions to the GLU.
26 If
<em class=
"parameter"><code>name
</code></em> is
27 <code class=
"constant">GLU_EXTENSIONS
</code>, then
<code class=
"function">gluGetString
</code>
28 returns a space-separated list of names of supported GLU extensions.
29 (Extension names never contain spaces.)
31 All strings are null-terminated.
