## DB->get_byteswapped()

    #include <db.h>

    int
    DB->get_byteswapped(DB *db, 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 returns a non-zero error value on failure and 0 on success.

### Parameters

#### isswapped

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.

### Errors

The `DB->get_byteswapped()` method may fail and return one of the following non-zero errors:

#### EINVAL

If the method was called before DB->open() was called; or if an invalid flag value or parameter was specified.

### Class
