ILockBytes::Flush
Ensures that any internal buffers maintained by the ILockBytes implementation are written out to the backing storage.
HRESULT Flush(void);
Return Values
S_OK
The flush operation was successful.
STG_E_ACCESSDENIED
The caller does not have permission to access the byte array.
STG_E_MEDIUMFULL
The flush operation is not completed because there is no space left on the
storage device.
E_FAIL
General failure writing data.
STG_E_TOOMANYFILESOPEN
Under certain circumstances, Flush does a dump-and-close to flush. This can lead to STG_E_TOOMANYFILESOPEN if
there are no file handles available.
STG_E_INVALIDHANDLE
An invalid floppy change has been made.
Comments
This method flushes internal buffers to the underlying storage device.
The OLE-provided implementation of compound files uses this method during a
transacted commit operation to provide a two-phase commit process that protects
against loss of data.
