#include <db_cxx.h>int DbMpoolFile::sync();
The DbMpoolFile::sync method writes all pages associated with the DbMpoolFile, that were marked as modified using DbMpoolFile::put or DbMpoolFile::set, back to the source file. If any of the modified pages are also pinned (i.e., currently referenced by this or another process) 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 which were modified but which DbMpoolFile::sync was unable to write.
In addition, 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.
