NAME

src/pmc/retcontinuation.pmc - Return Continuation

DESCRIPTION

RetContinuation extends Continuation.

A return continuation is a one shot Continuation. It gets recycled immediately after invocation.

void init(): Initializes the continuation.
PMC *clone: 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 get persistent until the GC gets at them.
opcode_t *invoke(void *next): Transfers control to the calling context, and frees the current context.
