lockunspent unlock ( [{"txid":"hex","vout":n},...] persistent )

Updates list of temporarily unspendable outputs.
Temporarily lock (unlock=false) or unlock (unlock=true) specified transaction outputs.
If no transaction outputs are specified when unlocking then all current locked transaction outputs are unlocked.
A locked transaction output will not be chosen by automatic coin selection, when spending dpowcoins.
Manually selected coins are automatically unlocked.
Locks are stored in memory only, unless persistent=true, in which case they will be written to the
wallet database and loaded on node start. Unwritten (persistent=false) locks are always cleared
(by virtue of process exit) when a node stops or fails. Unlocking will clear both persistent and not.
Also see the listunspent call

Arguments:
1. unlock                  (boolean, required) Whether to unlock (true) or lock (false) the specified transactions
2. transactions            (json array, optional, default=[]) The transaction outputs and within each, the txid (string) vout (numeric).
     [
       {                   (json object)
         "txid": "hex",    (string, required) The transaction id
         "vout": n,        (numeric, required) The output number
       },
       ...
     ]
3. persistent              (boolean, optional, default=false) Whether to write/erase this lock in the wallet database, or keep the change in memory only. Ignored for unlocking.

Result:
true|false    (boolean) Whether the command was successful or not
