• wszRestoreLogPath
  Input parameter. The location where the application will restore the log and patch files, and where the restore environment file is stored.

Return Value

The following return codes can be returned. To retrieve the error string for an ESE error, use the standard FormatMessage function. For the general errors hrErrorFromESECall and hrErrorFromCallbackCall, more information about the error is available using the standard GetLastError function.

S_OK	Success.
ESE-specific error codes	ESE-specific error codes, as defined in esebkmsg.h.
Other	Other Microsoft Win32® or remote procedure call (RPC) errors.

Remarks

Use this function when restoring a database that requires multiple restore sessions before the ESE can be allowed to recover the database state. This function is needed, for example, when restoring both a full backup and an incremental backup for a database.

The application must supply the wszRestoreLogPath parameter. This folder must contain an appropriate restore context file, which will be read by this function.

After finishing the restore operations, the application should call the HrESERestoreClose Function to close the connection and free the memory allocated by the HrESERestoreOpen Function.

Applications that use this function must be run under a user account that has Microsoft Windows® server operating systems Backup and Restore privileges.
