int
DB_ENV->lock_id_free(DB_ENV *env, u_int32_t id);

Description

The DB_ENV->lock_id_free method frees a locker ID allocated by the DB_ENV->lock_id method.

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

Errors

EINVAL

An invalid flag value or parameter was specified.

The locker ID is invalid or locks are still held by this locker ID.

The DB_ENV->lock_id_free 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_ENV->lock_id_free method may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
