-/**
- * Withdraw a coin from the exchange using a /reserve/withdraw
- * request.  This API is typically used by a wallet to withdraw a tip
- * where the reserve's signature was created by the merchant already.
- *
- * Note that to ensure that no money is lost in case of hardware
- * failures, the caller must have committed (most of) the arguments to
- * disk before calling, and be ready to repeat the request with the
- * same arguments in case of failures.
- *
- * @param exchange the exchange handle; the exchange must be ready to operate
- * @param pd planchet details of the planchet to withdraw
- * @param reserve_priv private key of the reserve to withdraw from
- * @param res_cb the callback to call when the final result for this request is available
- * @param res_cb_cls closure for @a res_cb
- * @return NULL
- *         if the inputs are invalid (i.e. denomination key not with this exchange).
- *         In this case, the callback is not called.
