darkcoind masternode outputs

darkcoind lockunspent

lockunspent unlock [{"txid":"txid","vout":n},...]

Updates list of temporarily unspendable outputs.
Temporarily lock (unlock=false) or unlock (unlock=true) specified transaction outputs.
A locked transaction output will not be chosen by automatic coin selection, when spending darkcoins.
Locks are stored in memory only. Nodes start with zero locked outputs, and the locked output list
is always cleared (by virtue of process exit) when a node stops or fails.
Also see the listunspent call

Arguments:
1. unlock            (boolean, required) Whether to unlock (true) or lock (false) the specified transactions
2. "transactions"  (string, required) A json array of objects. Each object the txid (string) vout (numeric)

         "txid":"id",    (string) The transaction id
         "vout": n         (numeric) The output number
       }
