mmioFlush
The mmioFlush
function writes the I/O buffer of a file to disk if the buffer has been written
to.
MMRESULT mmioFlush(
|
HMMIO hmmio, |
|
|
UINT fuFlush |
|
|
); |
|
Parameters
hmmio
File handle
of a file opened by using the mmioOpen function.
fuFlush
Flag
determining how the flush is carried out. It can be zero or the following:
|
MMIO_EMPTYBUF |
Empties the
buffer after writing it to the disk. |
Return Values
Returns zero
if successful or an error otherwise. Possible error values include the
following:
|
MMIOERR_CANNOTWRITE |
The
contents of the buffer could not be written to disk. |
Remarks
Closing a
file with the mmioClose function automatically flushes its buffer.
If there is
insufficient disk space to write the buffer, mmioFlush fails, even if
the preceding calls of the mmioWrite function were successful.
