<h2>Description</h2>
<p>
<code class="function">glBindTextures</code> binds an array of existing texture objects to a specified
number of consecutive texture units. <em class="parameter"><code>count</code></em> specifies the number of texture
objects whose names are stored in the array <em class="parameter"><code>textures</code></em>. That number
of texture names are read from the array and bound to the <em class="parameter"><code>count</code></em> consecutive
texture units starting from <em class="parameter"><code>first</code></em>. The target, or type of texture is
deduced from the texture object and each texture is bound to the corresponding target of the
texture unit. If the name zero appears in the <em class="parameter"><code>textures</code></em> array, any existing binding
to any target of the texture unit is reset and the default texture for that target is bound in
its place. Any non-zero entry in <em class="parameter"><code>textures</code></em> must be the name of an existing
texture object. If <em class="parameter"><code>textures</code></em> is <code class="constant">NULL</code> then it is as
if an appropriately sized array containing only zeros had been specified.
</p>
<p>
With the exception that the active texture selector maintains its current value,
<code class="function">glBindTextures</code> is equivalent to the following pseudo code:
</p>
<pre class="programlisting"> for (i = 0; i < count; i++) {
GLuint texture;
if (textures == NULL) {
texture = 0;
} else {
texture = textures[i];
}
glActiveTexture(GL_TEXTURE0 + first + i);
if (texture != 0) {
GLenum target = /* target of textures[i] */;
glBindTexture(target, textures[i]);
} else {
for (target in all supported targets) {
glBindTexture(target, 0);
}
}
}</pre>
<p>
Each entry in <em class="parameter"><code>textures</code></em> will be checked individually and if found
to be invalid, the state for that texture unit will not be changed and an error will be
generated. However, the state for other texture units referenced by the command will still
be updated.
</p>
</div>
<div class="refsect1" id="notes">
<h2>Notes</h2>
<p>
<code class="function">glBindTextures</code> is available only if the GL version is 4.4 or higher.
</p>
<p>
Note that because <code class="function">glBindTextures</code> cannot create new textures (even if
a name passed has been previously generated by call to <a class="citerefentry" href="glGenTextures.xhtml"><span class="citerefentry"><span class="refentrytitle">glGenTextures</span></span></a>),
names pased to <code class="function">glBindTextures</code> must have been bound at least once previously
via a call to <a class="citerefentry" href="glBindTexture.xhtml"><span class="citerefentry"><span class="refentrytitle">glBindTexture</span></span></a>.
</p>
</div>
<div class="refsect1" id="errors">
<h2>Errors</h2>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>first</code></em> + <em class="parameter"><code>count</code></em> is greater
than the number of texture image units supported by the implementation.
</p>
<p>
<code class="constant">GL_INVALID_OPERATION</code> is generated if any value in textures is
not zero or the name of an existing texture object.
