FlushViewOfFile
The FlushViewOfFile function writes to the disk a byte range within a mapped view of a file.
BOOL FlushViewOfFile(
LPCVOID lpBaseAddress,
| // start address of byte range to flush
| DWORD dwNumberOfBytesToFlush
| // number of bytes in range
| );
|
|
Parameters
lpBaseAddress
Points to the base address of the byte range to be flushed to the disk
representation of the mapped file.
dwNumberOfBytesToFlush
Specifies the number of bytes to flush.
If dwNumberOfBytesToFlush is zero, the file is flushed from the base address to the end of the mapping.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
Flushing a range of a mapped view causes any dirty pages within that range to
be written to the disk. Dirty pages are those whose contents have changed since
the file view was mapped.
