<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>.

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>

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>.
