int
DB_ENV->fileid_reset(DB_ENV *dbenv, const char *file, u_int32_t flags)

Description: DB_ENV->fileid_reset

The DB_ENV->fileid_reset method allows database files to be copied, and then the copy used in the same database environment as the original.

All databases contain an ID string used to identify the database in the database environment cache. If a physical database file is copied, and used in the same environment as another file with the same ID strings, corruption can occur. The DB_ENV->fileid_reset method creates new ID strings for all of the databases in the physical file.

The DB_ENV->fileid_reset method modifies the physical file, in-place. Applications should not reset IDs in files that are currently in use.

The DB_ENV->fileid_reset method may be called at any time during the life of the application.

The DB_ENV->fileid_reset method returns a non-zero error value on failure and 0 on success.

Parameters

file

The name of the physical file in which new file IDs are to be created.

flags

The flags parameter must be set to 0 or the following value:

DB_ENCRYPT

The file contains encrypted databases.

Errors

The DB_ENV->fileid_reset method may fail and return one of the following non-zero errors:

EINVAL

An invalid flag value or parameter was specified.
