const char *file, const char *database, u_int32_t flags);
The DB->remove method removes the database specified by the
file and database arguments. If no database is
specified, the underlying file represented by file is removed,
incidentally removing all databases that it contained.
Applications should never remove databases with open DB handles,
or in the case of removing a file, when any database in the file has an
open handle. For example, some architectures do not permit the removal
of files with open system handles. On these architectures, attempts to
remove databases currently in use by any thread of control in the system
The flags parameter is currently unused, and must be set to 0.
The DB handle may not be accessed again after DB->remove is
called, regardless of its return.
The DB->remove method returns a non-zero error value on failure and 0 on success.
- If a dbenv argument to db_create was specified, the
environment variable DB_HOME may be used as the path of the
database environment home.
DB->remove is affected by any database directory specified using the
DB_ENV->set_data_dir method, or by setting the "set_data_dir" string
in the environment's DB_CONFIG file.
The DB->remove method may fail and return a non-zero error for the following conditions:
- An invalid flag value or parameter was specified.
A database in the file is currently open.
Called after DB->open was called.
The DB->remove method may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
If a catastrophic error has occurred, the DB->remove method may fail and
in which case all subsequent Berkeley DB calls will fail in the same way.
