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, 0 on success, and returns DB_INCOMPLETE if there were pages that were modified but that DbMpoolFile::sync was unable to write immediately. 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 an exception encapsulating DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
