8 <code class=
"function">glGenTextures
</code> returns
<em class=
"parameter"><code>n
</code></em> texture names in
<em class=
"parameter"><code>textures
</code></em>.
9 There is no guarantee that the names form a contiguous set of integers;
10 however, it is guaranteed that none of the returned names was in use
11 immediately before the call to
<code class=
"function">glGenTextures
</code>.
13 The generated textures have no dimensionality; they assume the dimensionality
14 of the texture target to which they are first bound
15 (see
<a class=
"citerefentry" href=
"glBindTexture.xml"><span class=
"citerefentry"><span class=
"refentrytitle">glBindTexture
</span></span></a>).
17 Texture names returned by a call to
<code class=
"function">glGenTextures
</code> are not returned by
18 subsequent calls, unless they are first deleted with
19 <a class=
