enum node::ChainstateLoadStatus

strong

Chainstate load status.

Simple applications can just check for the success case, and treat other cases as errors. More complex applications may want to try reindexing in the generic failure case, and pass an interrupt callback and exit cleanly in the interrupted case.

		bool	wait_callback
	)

Submit a transaction to the mempool and (optionally) relay it to all P2P peers.

Mempool submission can be synchronous (will await mempool entry notification over the CValidationInterface) or asynchronous (will submit and not wait for notification), depending on the value of wait_callback. wait_callback MUST NOT be set while cs_main, cs_mempool or cs_wallet are held to avoid deadlock.

Parameters

[in]	node	reference to node context
[in]	tx	the transaction to broadcast
[out]	err_string	reference to std::string to fill with error string if available
[in]	max_tx_fee	reject txs with fees higher than this (if 0, accept any fee)
[in]	relay	flag if both mempool insertion and p2p relay are requested
[in]	wait_callback	wait until callbacks have been processed to avoid stale result due to a sequentially RPC. return error
