<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>.
