ExistsBerkeleyDatabase()

Here is the caller graph for this function:

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. May be a nullptr in rare cases if the wallet is in the process of being unloaded, its reference was already dropped but the BerkeleyEnvironment destructor is not yet done removing the environment from g_dbenvs.

Postcondition

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