CeFlushDBVol (RAPI)
This function flushes data written to a database volume on a remote Microsoft® Windows® CE–based device to permanent storage.
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 Values
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
RAPI method calls that access database volumes will fail on devices running in restricted mode unless the database permissions are explicitly set to allow RAPI access. For more information, see RAPI Restricted Mode Security.
