The mmioSetInfo function updates the information retrieved by the mmioGetInfo function about a file opened by using the mmioOpen function. Use this function to terminate direct buffer access of a file opened for buffered I/O.
Syntax
MMRESULT mmioSetInfo(
HMMIO hmmio,
LPCMMIOINFO pmmioinfo,
UINT fuInfo
);
Parameters
hmmio
File handle of the file.
pmmioinfo
Pointer to an MMIOINFO structure filled with information by the mmioGetInfo function.
fuInfo
Reserved; must be zero.
Return value
Returns zero if successful or an error otherwise.
Remarks
If you have written to the file I/O buffer, set the MMIO_DIRTY flag in the dwFlags member of the MMIOINFO structure before calling mmioSetInfo to terminate direct buffer access. Otherwise, the buffer will not get flushed to disk.
