Remarks

COM Signature

From textmgr.idl:

HRESULT IVsFileBackup::IsBackupFileObsolete(  
   [out] BOOL *pbObsolete  
);

IVsFileBackup needs to keep track of a secondary dirty bit for the backup in order to avoid extra backups for cases where the file is dirty, but the backup matches the current state of the object. This bit should be set when the object is modified and cleared on calls to BackupFile and any Save method. IsBackupFileObsolete returns true if this bit is set, false otherwise.
