gettxspendingprevout [{"txid":"hex","vout":n},...] ( {"mempool_only":bool,"return_spending_tx":bool,...} )
Scans the mempool (and the txospenderindex, if available) to find transactions spending any of the given outputs
Arguments:
1. outputs (json array, required) The transaction outputs that we want to check, and within each, the txid (string) vout (numeric).
[
{ (json object)
"txid": "hex", (string, required) The transaction id
"vout": n, (numeric, required) The output number
},
...
]
2. options (json object, optional) Options object that can be used to pass named arguments, listed below.
Named Arguments:
mempool_only (boolean, optional, default=true if txospenderindex unavailable, otherwise false) If false and mempool lacks a relevant spend, use txospenderindex (throws an exception if not available).
return_spending_tx (boolean, optional, default=false) If true, return the full spending tx.
Result:
[ (json array)
{ (json object)
"txid" : "hex", (string) the transaction id of the checked output
"vout" : n, (numeric) the vout value of the checked output
"spendingtxid" : "hex", (string, optional) the transaction id of the mempool transaction spending this output (omitted if unspent)
"spendingtx" : "hex", (string, optional) the transaction spending this output (only if return_spending_tx is set, omitted if unspent)
"blockhash" : "hex" (string, optional) the hash of the spending block (omitted if unspent or the spending tx is not confirmed)
},
...
