<p>src/pmc/retcontinuation.pmc - Return Continuation</p>
<h1><a name="DESCRIPTION"
>DESCRIPTION</a></h1>
<p><code>RetContinuation</code> extends <code>Continuation</code>.</p>
<p>A return continuation is a one shot Continuation.
It gets recycled immediately after invocation.</p>
<h2><a name="Methods"
>Methods</a></h2>
<dl>
<dt><a name="void_init()"
><b><code>void init()</b></code></a></dt>
Initializes the continuation.
<dt><a name="PMC_*clone"
><b><code>PMC *clone</b></code></a></dt>
Return a new Continuation PMC with the context of SELF.
Note: the returned object is not a RetContinuation and creating a real Continuation invalidates all RetContinuation all the way up the call chain.
That is,
these can't be recycled; they persist until the GC gets at them.
<dt><a name="opcode_t_*invoke(void_*next)"
><b><code>opcode_t *invoke(void *next)</b></code></a></dt>
Transfers control to the calling context and frees the current context.</dl>
