Berkeley DB: DB->get_byteswapped
DB->get_byteswapped
|
 |
#include <db.h>
int
DB->get_byteswapped(DB *db, int *isswapped);
Description: DB->get_byteswapped
The DB->get_byteswapped method returns if 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 has been
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
