GetWalletEnv()

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

Get BerkeleyEnvironment and database filename given a wallet path.

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.
