		const Txid &	txid,
		CMutableTransaction &&	mtx,
		std::vector< bilingual_str > &	errors,
		Txid &	bumped_txid
	)

Commit the bumpfee transaction.

Returns

success in case of CWallet::CommitTransaction was successful, but sets errors if the tx could not be added to the mempool (will try later) or if the old transaction could not be marked as replaced.

[in]	txid	The txid of the transaction to bump
[in]	coin_control	A CCoinControl object which provides feerates and other information used for coin selection
[out]	errors	Errors
[out]	old_fee	The fee the original transaction pays
[out]	new_fee	the fee that the bump transaction pays
[out]	mtx	The bump transaction itself
[in]	require_mine	Whether the original transaction must consist of inputs that can be spent by the wallet
[in]	outputs	Vector of new outputs to replace the bumped transaction's outputs
[in]	original_change_index	The position of the change output to deduct the fee from in the transaction being bumped
