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