Function Documentation

GetWalletEnv()

std::shared_ptr<BerkeleyEnvironment> GetWalletEnv	(	const fs::path &	wallet_path,
		std::string &	database_filename
	)

Parameters

[in]	wallet_path	Path to wallet directory. Or (for backwards compatibility only) a path to a berkeley btree data file inside a wallet directory.
[out]	database_filename	Filename of berkeley btree data file inside the wallet directory.

Returns

A shared pointer to the BerkeleyEnvironment object for the wallet directory, never empty because ~BerkeleyEnvironment erases the weak pointer from the g_dbenvs map.

Postcondition

A new BerkeleyEnvironment weak pointer is inserted into g_dbenvs if the directory path key was not already in the map.

IsWalletLoaded()

bool IsWalletLoaded

(

const fs::path &

wallet_path

)

Return whether a wallet database is currently loaded.

SplitWalletPath()

static void SplitWalletPath ( const fs::path &  wallet_path, fs::path &  env_directory, std::string &  database_filename  )

static

WalletDataFilePath()

fs::path WalletDataFilePath

(

const fs::path &

wallet_path

)

Given a wallet directory path or legacy file path, return path to main data file in the wallet database.
