lightning-reserveinputs -- Construct a transaction and reserve the UTXOs it spends
==================================================================================
SYNOPSIS
--------
2022-01-26 18:18:49 +01:00
**reserveinputs** *psbt* [*exclusive*] [*reserve*]
2020-06-10 02:20:18 +02:00
DESCRIPTION
-----------
The **reserveinputs** RPC command places (or increases) reservations on any
inputs specified in *psbt* which are known to lightningd. It will fail
with an error if any of the inputs are known to be spent, and ignore inputs
which are unknown.
2020-06-10 02:20:18 +02:00
Normally the command will fail (with no reservations made) if an input
is already reserved. If *exclusive* is set to *False*, then existing
reservations are simply extended, rather than causing failure.
By default, reservations are for the next 72 blocks (approximately 6
hours), but this can be changed by setting *reserve*.

RETURN VALUE
------------
[comment]: # (GENERATE-FROM-SCHEMA-START)
On success, an object containing **reservations** is returned. It is an array of objects, where each object contains:
- **txid** (txid): the transaction id
- **vout** (u32): the output number which was reserved
- **was\_reserved** (boolean): whether the input was already reserved
- **reserved** (boolean): whether the input is now reserved (always *true*)
- **reserved\_to\_block** (u32): what blockheight the reservation will expire
[comment]: # (GENERATE-FROM-SCHEMA-END)
On success, a *reservations* array is returned, with an entry for each input
which was reserved:
- *txid* is the input transaction id.
- *vout* is the input index.
- *was_reserved* indicates whether the input was already reserved.
- *reserved* indicates that the input is now reserved (i.e. true).
- *reserved_to_block* indicates what blockheight the reservation will expire.

On failure, an error is reported and no UTXOs are reserved.
The following error codes may occur:
- -32602: Invalid parameter, such as specifying a spent/reserved input in *psbt*.
