Forces the contents of the log to disk, at least up through the specified LSN.
At the very least, all records that have not yet been written to disk with an LSN less than or equal to lsnMinToForce must be written to disk now. An implementation may, however, choose to write more records than what is strictly required. For example, an implementation is allowed to force all records to disk, regardless of the value of lsnMinToForce. Passing 0 as lsnMinToForce indicates that the entire log is to be forced to disk.
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
The log may also be forced to disk after appending individual records. See ILog::AppendRecord.
A failure return value indicates that any records appended to the log since the last time it was successfully forced are not guaranteed to be on disk. The ILog interface does not provide a method to determine which records have been successfully written to disk. If you need to know which records were successfully written to disk, you must force the log for each record. See ILog::AppendRecord. It is recommended that you flush file buffers (for example, using the FlushFileBuffers function) before returning from this method.
