(current-continuation-structure)
Returns a transparent representation of the current continuation: a vector representing the innermost continuation frame. A field in the frame points to the parent frame, and so on.
(make-trampoline procedure)
Returns an environment-less procedure that takes any number of arguments and tail-calls procedure with those arguments.
It is not possible to create a procedure with a shorter procedure structure than that of a trampoline. That fact may be relied on: a trampoline can be patched into any other procedure.
(peek-bytes address buffer k)
Read k bytes from memory starting at address address and placing them in the bytevector buffer starting at index 0.
(poke-bytes address buffer k)
Write k bytes from bytevector buffer starting at index 0 to memory starting at address address.
