◆ EnsureDataDir()

void ArgsManager::EnsureDataDir ( ) const

If datadir does not exist, create it along with wallets/ subdirectory(s).

"/wallets" subdirectories are created in all new datadirs, because wallet code will create new wallets in the "wallets" subdirectory only if exists already, otherwise it will create them in the top-level datadir where they could interfere with other files. Wallet init code currently avoids creating "wallets" directories itself for backwards compatibility, but this be changed in the future and wallet code here could go away.
