◆ 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_pathPath to wallet directory. Or (for backwards compatibility only) a path to a berkeley btree data file inside a wallet directory.
[out]database_filenameFilename 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.
