<code class="function">glDeleteSync</code> deletes the sync object specified by <em class="parameter"><code>sync</code></em>. If the fence command

corresponding to the specified sync object has completed, or if no <a class="citerefentry" href="glWaitSync"><span class="citerefentry"><span class="refentrytitle">glWaitSync</span></span></a>

or <a class="citerefentry" href="glClientWaitSync"><span class="citerefentry"><span class="refentrytitle">glClientWaitSync</span></span></a> commands are blocking on <em class="parameter"><code>sync</code></em>,

the object is deleted immediately. Otherwise, <em class="parameter"><code>sync</code></em> is flagged for deletion and will be deleted when

it is no longer associated with any fence command and is no longer blocking any <a class="citerefentry" href="glWaitSync"><span class="citerefentry"><span class="refentrytitle">glWaitSync</span></span></a>

or <a class="citerefentry" href="glClientWaitSync"><span class="citerefentry"><span class="refentrytitle">glClientWaitSync</span></span></a> command. In either case, after

<code class="function">glDeleteSync</code> returns, the name <em class="parameter"><code>sync</code></em> is invalid and can no longer be used to

refer to the sync object.

</p><p>

<code class="function">glDeleteSync</code> will silently ignore a <em class="parameter"><code>sync</code></em> value of zero.

</p></div><div class="refsect1"><a id="notes"></a><h2>Notes</h2><p>

<code class="function">glSync</code> is only supported if the GL version is 3.2 or greater, or if

the <code class="code">ARB_sync</code> extension is supported.

</p></div><div class="refsect1"><a id="errors"></a><h2>Errors</h2><p>

<code class="constant">GL_INVALID_VALUE</code> is generated if <em class="parameter"><code>sync</code></em> is neither zero or the name of a sync object.
