<para>
<function>glGenTextures</function> returns <parameter>n</parameter> texture names in <parameter>textures</parameter>.
There is no guarantee that the names form a contiguous set of integers;
however, it is guaranteed that none of the returned names was in use
immediately before the call to <function>glGenTextures</function>.
</para>
<para>
The generated textures have no dimensionality; they assume the dimensionality
of the texture target to which they are first bound
(see <citerefentry><refentrytitle>glBindTexture</refentrytitle></citerefentry>).
</para>
<para>
Texture names returned by a call to <function>glGenTextures</function> are not returned by
subsequent calls, unless they are first deleted with
<citerefentry><refentrytitle>glDeleteTextures</refentrytitle></citerefentry>.
