BerkeleyDatabaseSanityCheck()

bool BerkeleyDatabaseSanityCheck

(

)

Perform sanity check of runtime BDB version versus linked BDB version.

Here is the caller graph for this function:

GetBerkeleyEnv()

std::shared_ptr<BerkeleyEnvironment> GetBerkeleyEnv

(

const fs::path &

env_directory

)

Get BerkeleyEnvironment given a directory path.

Parameters

[in]

env_directory

Path to environment 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.

MakeBerkeleyDatabase()

std::unique_ptr<BerkeleyDatabase> MakeBerkeleyDatabase	(	const fs::path &	path,
		const DatabaseOptions &	options,
		DatabaseStatus &	status,
		bilingual_str &	error
	)

Return object giving access to Berkeley database at specified path.
