The Db::get_byteswapped method
stores 0 into the memory location referenced by isswapped
if the underlying database files were created on an architecture of the
same byte order as the current one, and
stores 1 into the memory location referenced by isswapped
if they were not (that is, big-endian on a little-endian machine, or
vice versa). This field may be used to determine whether application
data needs to be adjusted for this architecture or not.
The Db::get_byteswapped interface may not be called before the Db::open
interface has been called.
The Db::get_byteswapped method may fail and throw an exception or return a non-zero error for the following conditions:
- An invalid flag value or parameter was specified.
Called before Db::open was called.
The Db::get_byteswapped 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 Db::get_byteswapped method may fail and
either return DB_RUNRECOVERY or throw a
in which case all subsequent Berkeley DB calls will fail in the same way.
