DbMpoolFile::sync

#include <db_cxx.h>
int
DbMpoolFile::sync();
Description
The DbMpoolFile::sync method writes all pages associated with the
DbMpoolFile, which were marked as modified using
DbMpoolFile::put or DbMpoolFile::set, back to the source file. If
any of the modified pages are also pinned (that is, this or
another process currently refers to them), DbMpoolFile::sync will
ignore them.
The DbMpoolFile::sync 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.
Errors
The DbMpoolFile::sync 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 DbMpoolFile::sync method may fail and
either return DB_RUNRECOVERY or throw a
DbRunRecoveryException,
in which case all subsequent Berkeley DB calls will fail in the same way.
