DB_MPOOLFILE->sync

#include <db.h> int DB_MPOOLFILE->sync(DB_MPOOLFILE *mpf); Description The DB_MPOOLFILE->sync function writes all pages associated with the DB_MPOOLFILE, which were marked as modified using DB_MPOOLFILE->put or DB_MPOOLFILE->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), DB_MPOOLFILE->sync will ignore them. The DB_MPOOLFILE->sync function returns a non-zero error value on failure, 0 on success, and returns DB_INCOMPLETE if there were pages that were modified but that DB_MPOOLFILE->sync was unable to write immediately. Errors The DB_MPOOLFILE->sync function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions. If a catastrophic error has occurred, the DB_MPOOLFILE->sync function may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
