CeFlushDBVol (RAPI) (Windows Embedded CE 6.0)

  • 项目

1/6/2010

This function flushes data written to a database volume on a remote Windows Embedded CE–based device to permanent storage.

Syntax

BOOL CeFlushDBVol(
  PCEGUID pceguid 
);

Parameters

  • pceguid
    [in] Pointer to the CEGUID that contains the globally unique identifier (GUID)of a mounted volume to be flushed.

Return Value

Nonzero indicates success. Zero indicates failure. To get extended error information, call CeGetLastError and CeRapiGetError.

Remarks

In a mounted database volume, all write operations are cached. To explicitly force the data to be written out to permanent storage, the CeFlushDBVol method must be called. If a reset or power failure occurs before data is flushed from the cache, then the data that has not been flushed is lost. The database engine periodically flushes the database volume when enough data has been changed and when it is unmounted, but an application that must ensure that its data is saved should call CeFlushDBVol

Requirements

Header rapi.h
Library rapi.lib
Windows Embedded CE Windows CE 3.0 and later
