#include <db_cxx.h> int Db::get_byteswapped(int *isswapped);
The Db::get_byteswapped() method returns
whether the underlying database
files were created on an architecture of the same byte order as the
current one, or if they were not (that is, big-endian on a
little-endian machine, or vice versa). This information may be used to
determine whether application data needs to be adjusted for this
architecture or not.
The Db::get_byteswapped() method may not be called before the
Db::open() method is called.
The Db::get_byteswapped()
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.
If the underlying database files were created on an architecture of the same byte order as the current one, 0 is stored into the memory location referenced by isswapped. If the underlying database files were created on an architecture of a different byte order as the current one, 1 is stored into the memory location referenced by isswapped.
The Db::get_byteswapped()
method may fail and throw a DbException
exception, encapsulating one of the following non-zero errors, or return one
of the following non-zero errors:
If the method was called before Db::open() was called; or if an invalid flag value or parameter was specified.
