<para>
<function>glDeleteSync</function> deletes the sync object specified by <parameter>sync</parameter>. If the fence command
corresponding to the specified sync object has completed, or if no <citerefentry><refentrytitle>glWaitSync</refentrytitle></citerefentry>
or <citerefentry><refentrytitle>glClientWaitSync</refentrytitle></citerefentry> commands are blocking on <parameter>sync</parameter>,
the object is deleted immediately. Otherwise, <parameter>sync</parameter> is flagged for deletion and will be deleted when
it is no longer associated with any fence command and is no longer blocking any <citerefentry><refentrytitle>glWaitSync</refentrytitle></citerefentry>
or <citerefentry><refentrytitle>glClientWaitSync</refentrytitle></citerefentry> command. In either case, after
<function>glDeleteSync</function> returns, the name <parameter>sync</parameter> is invalid and can no longer be used to
refer to the sync object.

<function>glDeleteSync</function> will silently ignore a <parameter>sync</parameter> value of zero.
