DbEnv::lock_id

#include <db_cxx.h> int DbEnv::lock_id(u_int32_t *idp); Description The DbEnv::lock_id method copies a locker ID, which is guaranteed to be unique in the specified lock table, into the memory location referenced by idp. The DbEnv::lock_id method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success. Errors The DbEnv::lock_id method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the DbEnv::lock_id method may fail and either return DB_RUNRECOVERY or throw an exception encapsulating DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
