Db::get_byteswapped

#include <db_cxx.h> int Db::get_byteswapped(int *isswapped); Description 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 be called only after the Db::open interface has been called. Errors The Db::get_byteswapped method may fail and throw an exception or return a non-zero error for the following conditions: EINVAL 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 an exception encapsulating DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
